I need a complete website built around display advertising for products. The core idea is simple: advertisers create visually engaging product ads and customers browse, click, and interact with them. To make that work I’ll need two distinct account types—one for advertisers to upload, schedule, and track their campaigns, and another for customers so they can manage preferences, save favorite ads, and receive a more personalized experience. I’m open on the tech stack as long as the final site is fast, mobile-responsive, and easy for me to maintain without touching code every day. A clean dashboard for me (as the admin) is essential so I can approve or reject ads, set pricing rules, and pull basic analytics. Key deliverables: • Fully functional website front-end and ...

I am looking for an experienced backend developer to build a Service Booking Automation System on WhatsApp. The project involves connecting users with service providers using AI parsing and automated workflows. We are not building a mobile app. This is a pure WhatsApp Automation project using official APIs. Core Technical Requirements: WhatsApp Business API Integration: Experience with BSPs (like Interakt, Wati, or Twilio). AI Integration: Connect OpenAI (GPT-4) to parse unstructured user messages (e.g., extracting date, location, and intent from chat). Database Management: Proficiency in Supabase (PostgreSQL) to store user data and active requests. Geolocation Logic: Ability to filter database entries based on "Location Pins" (Lat/Long) shared on WhatsApp. Broadcast & Timer ...

I need a single web-based dashboard that lets commercial facility managers see, at a glance, how each of their solar PV systems is performing. The interface must pull live data through the public or partner APIs of SolisCloud, Fusion Solar, Growatt, Solar Analytics, iSolarCloud and Wattwatchers, then store that data in a database I can host myself—PostgreSQL or another non-proprietary option preferred so I can avoid ongoing subscription fees. For the first release I only require on-screen visualisation (no PDF or emailed reports). The screen should surface the core indicators we usually follow—energy production, energy consumption and overall system efficiency—while leaving room for us to add or hide additional metrics later. Charts, comparative widgets and clear status ...

Project Overview – Barbershop Booking & Management App This project is inspired by Booksy (customer app) and Booksy Biz (business app), but the goal is to combine both into a single application with role-based access instead of two separate apps. The platform serves three user roles: • Customer • Barber / Staff • Owner Each role sees different features and dashboards inside the same app. I already have an APK build available that shows: • The current UI/UX direction • Existing screens and flows • Features that are already partially implemented The APK and screenshots are provided as a reference to speed up development, not to redesign everything from scratch. The expectation is to continue, improve, and complete what’s already starte...

I’m setting up a fresh backend that will house our analytics data, and I want it built around MySQL. The work starts with solid database architecture—clean schema design, indexing strategies, partitioning where it makes sense, and clearly documented relationships so future queries remain fast even as volume grows. Once the structure is in place, I need automated pipelines to move data from our various sources into this new store. Think full-stack ETL: extract from APIs or flat files, transform for consistency and quality, then load into the MySQL tables on a defined schedule. I’m open to tools you’re comfortable with—Python scripts, Airflow, Fivetran, or a light-weight custom solution—as long as the result is reliable, monitorable, and easy to extend....

I keep hitting a connection-timeout message whenever I try to reach my PostgreSQL database from the terminal with psql. The database is part of a Dockerised backend; the application layer spins up fine, yet a direct CLI connection fails as though the server does not exist. I have not even confirmed whether the PostgreSQL container is actually running because I am unsure of the correct Docker commands to use or the places to look for port-mapping issues. What I need is straightforward: trace the reason the terminal session can’t find the server, bring the database online (or exposed) if it is down or mis-configured, and leave me with the exact commands or config edits required so I can repeat the process on other environments. Deliverables • Working psql connection from my lo...

(This is not a real Project, If hired you will be training an individual in completing the following tasks, You will be paid to train) I’m extending an existing C#/.NET solution that drives sensor-based PCBs on the lab bench and streams the resulting measurements into a PostgreSQL back-end. What I need now is a specialist who can tighten the link between the physical devices and a truly high-volume data pipeline. The hardware side The application already communicates with multiple sensor-laden PCBs over standard interfaces (USB-TTL and TCP sockets). Your task is to refine those drivers so they stay rock-solid during long endurance tests—handling hot-plug events, reconnection logic and precise timing so no sample is lost. The data side We routinely push hundreds of thousan...

Our team is midway through building a Electronic Health Record (EHR) platform and the PostgreSQL layer now needs an expert touch. The schema has grown organically; I need someone with 5+ years of solid PostgreSQL experience who can step in, refine the data model, and leave us with a fast, future-proof database. Your first task will be to review the existing ERD and propose improvements that align with our integration workflows. From there, you’ll redesign tables, constraints, and indexes where necessary, write or refactor the complex SQL that feeds our pipelines, and tune the engine so queries fly. Back-ups and routine maintenance scripts also need tightening to guarantee reliability once we go live. I’m working on a fixed, project-based arrangement and expect clear milestone...

I have three separate ideas that I want to turn into fully-functioning Odoo 19 solutions. Each project will be delivered as its own installable module, deployed on a fresh Odoo 19 instance that I will provide.

I have a PostgreSQL 11 (or newer) instance running as a Windows service, and I’d like to switch its user authentication from the default method to our already-operational LDAP directory. The LDAP server is up and reachable on the network; I simply need the database side wired correctly so that log-ins are validated against LDAP instead of local roles. The work involves: • Editing and any relevant parameters in to enable LDAP authentication and reloading the service without downtime. • Verifying connectivity, binding credentials and search patterns. • Walking me through a quick test with psql or pgAdmin to confirm that an LDAP user can connect and a non-LDAP user is rejected. • Supplying a short note (markdown or text) summarising the final configuration s...

I want to launch an Android-first replica of that fuses real-cash gaming with a built-in shopping credits system. Players top up a wallet, enter skill- or chance-based games, and—if they don’t win—every rupee automatically converts to shopping credits that can be spent in the app’s store. Instant withdrawal of winnings is equally important, so the wallet flow must handle both directions seamlessly. Core scope • Android MVP ready for Google Play within 4–8 weeks, polished enough to earn early user reviews and retention metrics. • iOS codebase planned next, so whatever stack you choose should keep cross-platform portability in mind. • Mandatory phone-number + OTP authentication out of the box.

I need a Python-powered web application that lets retail traders screen live market data, choose a trading condition from the built-in library, and send orders instantly to three brokerage partners—Broker A, Broker B and Broker C—through their official REST/WebSocket APIs. The interface must feel interactive and feature-rich rather than bare-bones; think live, auto-refreshing tables, dynamic charts and a responsive layout that works on desktop first but scales to tablets. Core workflow 1. Real-time market feed arrives, is processed and filtered by my screening rules (I will provide the initial rule set in JSON). 2. When a rule is triggered the user should be able to preview and edit the trade ticket (quantity, price, stop etc.). 3. On confirmation the app sends the appro...

I’m building a cryptocurrency trading platform and need a developer who can own the portfolio-management side of the product. The core of your work will be a module that lets users see every position across connected exchanges in real time, then runs meaningful risk assessment on top of that data. Here’s what I have in mind: once a user links an API key, the system should pull balances and trade history, store everything in PostgreSQL, and continuously calculate exposure metrics—value at risk, asset and sector concentration, drawdown, even a quick stress-test against historic crashes. When a threshold is breached, users receive an alert straight inside the React dashboard (and optionally by email or push). The order-execution engine is already under development; you&rsq...

I already have the complete Laravel application archive waiting in a Git repo, but the VPS it should live on is still a blank slate. I need you to turn that empty server into a fully working production environment, install the script, and make sure the built-in admin panel (its default features are enough) is reachable at /admin. Work starts with the VPS itself: set up the web stack (PHP 8+, Composer, Nginx or Apache, MySQL/PostgreSQL—whichever you find optimal), secure the box, create a non-root deploy user, and harden SSH. Once the base is stable, clone or upload the project, run composer install, set up the .env, generate the key, migrate & seed the database, and wire up queue workers or schedulers if the app needs them. A free SSL certificate from Let’s Encrypt should ...
