Da 165,234 valutazioni, i clienti danno una valutazione ai nostri API Developers di 4.9 stelle su 5Voglio lanciare un nuovo store su Shopify con un look elegante e professionale. Cosa mi serve: • Configura da zero il negozio, scegliendo o personalizzando un tema coerente con un’estetica raffinata. • Struttura al massimo 1-5 categorie di prodotto e importa il catalogo dal mio fornitore di dropshipping. • Integra il sito del fornitore (API, app o feed CSV) in modo che ogni ordine parta automaticamente verso di lui per la spedizione. • Collega e sincronizza lo shop con TikTok Shop: catalogo, scorte e tracking ordini devono aggiornarsi in tempo reale. • Attiva le modalità di pagamento che ho scelto: carta di credito/debito tramite Shopify Payments e PayPal. • Esegui test completi di checkout, flusso ordine-fornitore e tracciamento spedi...
I need a developer who knows BigCommerce inside-out to extend the store’s core functionality. The immediate focus is shipping logic: I want new shipping methods added, existing rates adjusted, and clear zone-based rules so customers see the right options every time they check out. Changes must be configured in the control panel rather than hard-coded, so I can edit them later without touching code. Alongside shipping, product pages require more flexible variations. Think custom option sets that handle complex combinations cleanly, keep inventory in sync, and present a smooth selector on Stencil templates. Deliverables • New shipping methods visible at checkout and in the admin panel • Rate tables updated and verified for accuracy across all defined zones • Zone...
I need Grafana and Prometheus installed and fully configured from scratch, then Prometheus (with the usual Node Exporter) deployed on my remote Linux server so it can scrape the host and forward data. Once data is flowing, I want a clean, responsive Grafana dashboard that shows at a glance: CPU load, memory usage, disk space, inbound/outbound network traffic and total server uptime. I’m not sure yet whether we’ll add any custom metrics, so please leave the configuration flexible enough for future exporters or additional PromQL queries. Key deliverables: • Fresh installation and secure basic configuration of Prometheus and Grafana • Prometheus service running on the remote Linux server with Node Exporter enabled • Verified data collection and target heal...
If you are expert in building Oracle AI agents and if you have the fusion experience then only bid this project. payment will be released only if the project satisfied or else no payment. it needs to be remote work you just need to guide me i will do in my system. I have a Fusion Application instance and want to layer Oracle AI Agent Studio on top of it so that key customer-facing actions happen automatically. The flow is straightforward: • The agent picks up promise dates and status changes from Fusion. • It updates the relevant “Notes” field in real time. • If a promise is missed, the agent triggers an email to the customer (and a copy to our team). Few of theAPI keys are already available; I simply need you to wire them into Oracle AI Agent Studio, c...
I’m running a Laravel 10 bulk-media sender that talks to WhatsApp Business Cloud through a webhook. Whenever the API answers with HTTP 429, the webhook does mark the message as failed, yet the queued retry flow (RetryFailedWhatsAppJob on Redis/cloud queue) rarely fires, and when it does, the image-ID matching logic sometimes mis-aligns. The result is missed retries or, worse, duplicate sends. Here’s what needs to happen: • Repair the webhook callback so the media object returned by WhatsApp is always matched to the correct outbound record. • Ensure the job is dispatched, picked up, and processed on the existing Redis-backed queue every time a 429 occurs, honouring the current attempt counter. • Implement a reliable back-off for those 429 responses so we r...
My stock-trading web app is showing real-time prices that don’t match the figures streaming through my broker’s terminal. The terminal’s feed is correct; the web app injects incorrect numbers and they drift further off the longer the session stays open. I need someone who has already debugged exchange or broker APIs, websocket feeds, or similar market-data pipelines and can pinpoint why the values pushed to the browser diverge. You may have to inspect the feed handler, caching logic, time-sync, or any rounding and conversion routines in the JavaScript front end as well as the server-side code. Acceptance will be simple: with the fix in place, the web app must display the same tick-for-tick price as the broker’s terminal during a live market session. If you&rsquo...
I need my existing WordPress-based portal rebuilt on a modern .NET stack while keeping every core capability visitors already rely on—user registration and login, the full content-management/blogging workflow, and our current e-commerce flow. The assignment covers more than a straight port: once the core experience is re-implemented, I also want richer analytics and reporting, stronger security hardening, and seamless hooks into selected third-party services so the new platform launches with clear business insight, tighter protection, and future-ready integrations. You will work against a PostgreSQL back end; no other database is required. All existing WordPress data—users, posts, media, products, orders, and settings—must transfer intact, with zero visible downtime to c...
I need a complete n8n configuration that ties several data sources together and runs reliably in production. The workflow must talk to multiple APIs, pull information from our databases, and work with our cloud-storage buckets. Through those API connections it should be able to fetch data, send new records, and update existing ones so the different systems stay in sync without manual intervention. Here is the flow I have in mind: • Trigger: a schedule or webhook that starts the job. • Data collection: fetch fresh records from the relevant APIs and query the database for any matching or missing entries. • Processing layer: transform or enrich the raw payload (basic validation, mapping, de-duplication). • Storage & sync: write the cleaned data back to the data...
ATTENTION: I am looking for a high-performing Individual Lead Developer. No agencies. No task-completers. If you are unreliable, unpunctual, or expect to be micromanaged, do not apply. I need a technical partner who takes ownership and is hungry to build a world-class product. The Project A sophisticated, closed-community platform for professional networking and high-performance collaboration (Stealth Mode). The Figma designs are 100% complete and high-fidelity. I need a "premium" implementation: fluid animations, micro-interactions, and flawless native performance for iOS and Android. The Goal: A fully functional, polished V1.0 ready for App Store and Google Play Store submission. Core Scope for V1.0 Launch: 1. Security & Access: Robust Whitelist System (Domain-based &am...
My project is roughly 80 % complete, and I’d like an experienced Bubble developer to bring it over the finish line so I can deploy. The core build is solid, but several key features are still missing or half-done. Here is exactly what I still need: • Square payment integration fully wired up, including test mode, error handling, and production keys. • Broken footer links fixed so every link resolves to the correct page. • Percentage-based discount / coupon system that lets me create, activate, and expire codes from the admin side. • Admin panel polished: intuitive navigation, role permissions, user search, and basic analytics. • Clear separation between Individual and Business accounts (different onboarding flows, database fields, and dashboard vie...
I’d like to turn my stock-market ideas into an AIML pattern–driven trading bot that can watch live prices, analyse them on the fly, and place orders automatically while staying within clear risk limits. The core logic must be written around AIML so that trading rules can be updated simply by editing or adding patterns rather than rewriting code. Scope • Data feed & brokerage connection: connect to reliable real-time stock quotes and an API that allows live order execution. • AIML engine: ingest my pattern files, match market conditions, and trigger buy/sell signals. • Strategy design: please propose robust, back-testable strategies suitable for liquid equities; optimisation and walk-forward testing are expected. • Risk layer: position sizing, st...
I need help collecting a clean, well-structured list of Twitter accounts that consistently post about AI and possibly category of AI (open source, ML, AI, general AI) Instead of handing you a fixed list, I’ll define the selection rules (for example: minimum follower count, specific AI-related keywords, recent activity, etc.) - min follower count 5000 and have alteast multiple posts with 100+ likes/ retweets. Once those criteria are agreed on, you’ll locate the matching profiles and extract two data points per account: • the public profile bio • the direct profile link (around 1M+ profiles) Please return everything in a single CSV file, one row per influencer. Feel free to use Python, Tweepy, Twitter API v2, ScraperAPI, or another reliable method—as long...
I’m setting up a brand-new online store and want the entire build to run on Medusa JS. From the ground up I need: • Product catalog management that supports advanced inventory with variants (sizes, colors, bundles, etc.) • A smooth shopping-cart experience tied to a secure payment gateway • A fresh, custom design—there’s no existing wireframe, so you will shape both the look and the structure You’ll own the Medusa server configuration and extend it where necessary for variant logic, stock tracking, and order flows. On the front end, the goal is a clean, responsive storefront that showcases products clearly and converts well; I’m open to the stack you prefer as long as it pairs seamlessly with Medusa’s APIs. Acceptance criteria &bu...
I’m building an Android-only application and need a clean, secure login flow that relies on one-time passwords sent strictly by SMS. Users will enter their phone number, receive the code, and gain access after successful verification—no usernames or emails involved. You’ll be responsible for wiring up the full authentication cycle, choosing a reliable SMS gateway, and writing the Android code (Kotlin or Java—your call) that: • accepts the phone number, • triggers the SMS OTP dispatch, • validates the returned code with sensible expiry and limited retries, • handles resend logic, and • stores / refreshes session tokens once the user is verified. Deliverables must include the documented source code, any backend or cloud function n...

I need an experienced Python trading-bot developer to optimize and refactor a live async trading bot connected to REST & WebSocket APIs, which currently slows under load and misses ticks/orders. The task includes profiling bottlenecks, improving async/WebSocket performance, optimizing pandas & SQLite usage, and ensuring real-time execution. Goal: <200 ms tick-to-order latency, zero missed ticks, clean refactored code, tests, and one-command VPS setup.
Trabajo diariamente con un sistema de tickets (osTicket) para gestionar siniestros. Quiero que el flujo sea completamente automático: 1. debe consultar la API de osTicket para leer tanto los estados de los tickets como su historial. 2. Con esa información, Make tiene que lanzar una llamada saliente a través de Vapi cuya única finalidad será actualizar el estado del ticket directamente desde la llamada. Espero al final del proyecto un escenario totalmente funcional en , la autenticación y mapeo correcto con la API de osTicket, y el módulo de Vapi configurado para que la llamada ejecute la actualización sin intervención manual. Cualquier código, rutas de webhook, documentación breve de instalación y pru...
I'm currently facing a problem with the login functionality of my website/application. It was working fine, after some server side upgrade (probably php) from my hosting company this issue started. While creating user registration the pages get skipped and not getting completed. This needs to be fixed. After fixing, other few modifications should also be done. Below are the detail: • Fix Registration – Activate user signup/login (for two websites - stopped working after hosting/php upgrade). • Modify Admin Panel – Show total users, course-wise stats, expiry list, manual activation/deactivation, etc., and 100-day course expiry logic. • Paid Course Automation – Auto-activate courses via Razorpay web hook (razorpay account available) + WhatsApp welcome...

****** READ THIS BEORE BIDDING ****** I won't pay more than $30 AUD for this project. If you bid more than this, I will block you permenantly. I don't work with people who don't follow briefs. You've been warned. HERE'S THE JOB: I accidentally deleted the scenario that linked my VAPI voice bot, and the AI wallet that covers usage fees. I simply need that connection re-established and, while you are in there, a tiny tweak made so VAPI spells out an email address instead of speaking it as a single word. The set-up worked flawlessly before, so all the pieces—VAPI, and my existing AI—are already in place. I just can’t spare the time to retrace the previous wiring. From experience this is a sub-20-minute task for someone who understands both...

Plaid + Chase Connectivity Issue via API Plaid + Chase OAuth Integration — "Invalid Credentials" After Successful OAuth Flow The Problem: We have a production Plaid integration (Node.js/Express) that connects bank accounts via Plaid Link. American Express and Capital One connect and sync perfectly. Chase fails every time with "Username or password incorrect" AFTER the OAuth flow completes successfully. The Flow: 1. User clicks Connect Bank → Plaid Link opens 2. User selects Chase → Plaid fires OPEN_OAUTH event 3. User redirects to Chase's website and logs in successfully 4. Chase redirects back to our app with oauth_state_id 5. Plaid Link re-opens with receivedRedirectUri 6. Plaid shows "Username or password incorrect" — connectio...
Tenho hoje o ChatPion funcionando, porém preciso levá-lo a outro nível. Estou aberto a duas vias: aprimorar diretamente o ChatPion ou, caso seja tecnicamente mais simples, desenvolver um novo chatbot do zero para minhas páginas do Facebook. O que é indispensável • Envio de mensagens em massa sem limites artificiais, inclusive para várias páginas simultâneas. • Integração com outras plataformas (APIs externas, CRM, e-commerce ou o que for necessário). • Respostas automáticas mais inteligentes, capazes de entender variações de texto e entregar conteúdo personalizado. Além disso, quero um painel central onde eu consiga disparar campanhas, alterar configu...
I have the complete source code for BDonor, a live web-app that is currently down because Clerk Auth hit its “100 user limit.” The break means I can’t even reach the admin panel, so I need a clean redeployment from the ground up. Right now the site is hosted on Vercel, but I’m open to keeping it there or shifting to something like AWS or Google Cloud if that would eliminate the Clerk ceiling and future-proof the project. I’m not certain which environment variables, build flags, or third-party hooks are mission-critical, so I’ll rely on your guidance to audit the repo, document what matters, and carry it over correctly. Key objectives • Spin up a fresh production instance under my own new accounts (hosting, auth, database, any other services). &b...

I have an existing Google Sheet that already captures the core data for my project. What I now need is a lightweight web app—built in HTML, CSS and JavaScript (or Google Apps Script HTML Service)—that connects to this sheet for real-time reading and writing. Here is how I picture the flow: • A clean, responsive front-end form where users can enter or edit records. • Direct integration with the current Google Sheet via Apps Script, the Sheets API, or whichever approach you find most efficient. • Basic navigation that lets me expand later into dashboards or reports. You will work alongside me, sharing code in a version-controlled space (GitHub or similar) so we can iterate quickly. I can supply the Sheet structure, sample data and access credentials as soon ...
I have Apple Pay enabled through Shopify Payments and the button shows up on every product page, but when a customer taps it the site jumps to the regular checkout instead of opening the Apple Pay sheet and completing the purchase in place. The payment never processes, and the same behaviour occurs on iPhone, iPad, Mac, Safari, and Chrome, so it isn’t a device-specific glitch. What I need is a clean repair or re-implementation of Apple Pay on the product detail page so the flow stays on the PDP, the Apple Pay modal opens, the charge is authorised, and the order is created in Shopify without any manual redirects. Please work directly in the theme (Liquid, JavaScript) or via Shopify’s Payments API—whatever is best practice—while keeping existing styling untouched. I...

I’ve just finished deploying a new Android mobile application and everything appeared to go smoothly—until I tried to launch it. Right after installation the app attempts to talk to the backend and immediately throws a server error. The APK itself installs without complaint; the trouble starts only once the first request is sent. I need someone to dive in, locate the root cause on the server side, and implement a clean fix so the app can connect reliably every time. Access to the server, source code, and crash logs is ready for you as soon as we agree to move forward. Please bring experience with common Android back-end stacks (Node, PHP, Java, or similar) and a methodical debugging approach. Once resolved, I’ll confirm the build installs and runs error-free on multiple ...

The project is to build a Python-based bot that trades equities on NYSE, NASDAQ, and AMEX. It must run end-to-end without manual intervention: gathering live market data, analysing it in real time, placing orders, and continuously enforcing risk limits. Core functionality • Automated trade execution driven by a configurable strategy engine • Real-time market analysis with fast data ingestion (websocket or streaming API) • Built-in risk management: position sizing, max draw-down and stop-loss rules Technical notes Python is mandatory; common libraries such as pandas, NumPy, TA-Lib, and asyncio are expected. The code should be clean, modular, and ready to plug into broker APIs like Interactive Brokers, Alpaca, or Tradier. A lightweight front-end (CLI or simple dashbo...

My WooCommerce-powered WordPress site already generates its own backups; what I am missing is a plugin that quietly copies those archives to a remote device of my choosing. The workflow I have in mind is simple: • Scheduling – I need to set a daily schedule with at least three runs per day, plus the freedom to change the hour, frequency, and how many archives are retained. • Source & destination paths – both must be selectable from the admin panel so I can point to the existing local backup folder and the remote target. • Secure hand-off – the connection between server and remote device will be authenticated with an API key that I provide. A second key (or the same key in a different scope) should protect the device itself. • Reliability logic ...
I need a small, Windows-friendly Python script that will open a real browser with Selenium and wipe large batches of content from my X (Twitter), Facebook, and Instagram accounts. Because my X account sits on the free API tier I keep running into 403 errors, so this project must rely solely on browser automation—no official APIs or paid third-party tools. Here’s what I’m after: the script launches from the command prompt, asks for (or reads from a .env) my login credentials, signs in, and then iterates through all visible posts, tweets, and reels, deleting each one until none remain or until it hits an optional stop condition such as a date or a post count I can set. A simple console printout like “Deleted tweet #42” is enough for logging; I don’t need ...
IM TYRING TO RUN THE ATTACHED JPNY SCRIPT TO GET INFO FROM A WEBSITE BUT I CANT UNDERSTAND IT DOESN'T WORK. I NEED THIS SCRIPT TO BE FIX + PAGINATION TO FETCH AROUND 2400 RECORDS FOR YELLOWPAGES I ONLY USE JUPYTER
I have a working Python script that talks to the Kalshi prediction-market API, pulls live data, and fires off trades automatically through simple web-request helpers. Functionally it looks solid from my end, but I’m not a developer and would like an expert eye on it before I trust it with larger positions. The review should cover every critical angle—accuracy of the trading logic, efficiency of each call or loop, and robust error-handling so a bad response or network hiccup never leaves an order hanging. Because the script relies heavily on APIs and a small amount of web-scraping, please verify that authentication, rate-limit handling, and data parsing follow best practices and won’t put the account at risk. Deliverables • A line-by-line code review (commented or...
Universal ACH Payment System Technical Build Guide, User Tutorial & Best Practices 1. Purpose & Vision This document defines a universal, automated ACH-based payment system designed to track, label, route, and reconcile all incoming and outgoing cash flows across personal and business entities. The system is accounting-led, automation-first, and scalable from small recurring loans to institutional-level operations. 2. Core Design Principles • ACH rails are passive; intelligence lives in the ledger and automation layer. • All funds flow through a small number of hub accounts. • Every transaction must carry a structured identifier. • QuickBooks (or equivalent GL) is the system of record. 3. System Architecture Overview The system consists of five layers: Bank Hub...
Whenever a customer completes an online purchase on my WooCommerce-powered WordPress site, the Order Source column in the admin panel displays “unknown” instead of the usual “Web” (or similar). All of these transactions are processed through the Cashfree gateway, and I have not installed or updated any plugins recently, so the environment has been stable for a while.
