I represent a marine-sector company that now needs a full digital presence—far more than a brochure site. The goal is to deliver a polished corporate website supported by an online booking engine, a content-management system our staff can run without developers, and a secure client portal that streamlines every post-booking interaction. Scope of work • Design and build a modern, mobile-first corporate website that conveys our authority in the maritime industry and is easy to navigate. • Create an end-to-end booking platform where customers can view availability in real time, select services, complete payment, and instantly receive confirmation. • Provide a CMS with role-based access so marketing and operations teams can update pages, rates, and schedules on thei...
The project centres on a streamlined, secure web platform that lets individual borrowers handle every step of a small-ticket loan online, while giving my internal team full oversight from the admin side. The front-end must be responsive so applicants can comfortably use desktop or mobile, and the back-office should feel equally intuitive for staff processing dozens of files a day. Borrower portal – required modules • Loan application form with basic KYC upload • Real-time loan status tracking once a request is submitted • Clear repayment schedule that updates automatically after disbursement Admin panel – required modules • User management (create / edit / suspend borrower accounts) • Loan approval workflow with status gates (review →...
Our production-level Node.js app has suddenly begun returning an HTTP 500 Internal Server Error whenever a REST POST request hits one of the API endpoints. All other request types appear stable, so I’m convinced the fault sits somewhere in the endpoint logic rather than in server configuration or the database layer. What I need you to do is jump straight into the codebase, trace the exact break point, and deliver a clean, documented fix that brings every POST route back to life. is the framework in play, alongside typical middleware for authentication and database access, so familiarity there will speed things up. Robust debugging, readable commits, and regression tests are all non-negotiable because the patch will go directly into production once it passes QA. Deliverables &bul...
I need a purpose-built B2B e-commerce portal that allows corporate clients and our field sales representatives to interact inside a single, secure environment. Unlike a standard storefront, the site should emphasise relationship management: every user signs up, lands on the appropriate dashboard, and can start a private conversation thread with the rep assigned to them before any order is placed. Core workflow I have in mind: • User registration & profile creation for two roles—client and sales rep. • Internal messaging so both sides can discuss pricing, availability and order details in real time. (We already manage product data in-house, so a full catalogue can be added later; the immediate focus is on the people connection.) The underlying platform simply needs...
I need a seasoned .NET backend developer to build a suite of RESTful APIs that will power our next release. The core of the job is pure API development—no UI work—so you should feel completely at home writing clean, well-structured C# code in .NET (preferably .NET 6 or later), wiring it up with Entity Framework or Dapper for data access, and documenting everything with Swagger / OpenAPI. Here’s what the APIs must handle: • User authentication (token-based, ideally JWT) • Full CRUD operations for our primary data models • Smooth third-party integrations, starting with two vendors that expose JSON endpoints I’ll provide the database schema, access credentials, and a concise list of integration endpoints on kickoff. You’ll return: 1. So...
My production C# application currently targets .NET Framework 4.8 and has started to show its age. I need it migrated to a supported, more secure runtime (ideally the latest LTS release of .NET), with every dependency updated and any obsolete APIs refactored. The primary driver is security: I want all outstanding vulnerabilities removed, HTTPS enforcement tightened, and modern authentication/cryptography practices adopted throughout the codebase. During the upgrade I also want to introduce a clean integration layer so the app can talk to external systems (REST and, if feasible, simple message-queue endpoints). This should be implemented in a way that keeps the core logic decoupled and unit-testable. Finally, a handful of persistent UI glitches—visual misalignments and sporadic cont...
I’m ready to move my Paying-Guest/hostel operations off spreadsheets and into a single, web-based platform built with .NET (C#), SQL Server or MySQL, HTML, CSS and JavaScript. The application will sit on a hybrid setup—part cloud, part on-prem—so clean separation of concerns and a painless deploy script are important. Core scope • Secure, role-based authentication for Owners, Students and Administrators, each landing on a tailored dashboard. • Property and room management with live availability, quick search and filters. • Student self-registration followed by a guided room-booking flow that updates availability in real time. • Integrated rent ledger: capture payments, show history, flag overdue amounts and let me export or print offline recei...
I need a website that brings two sides of my practice together: data-driven analysis and strategic business consultancy. On the analytics side the site must present interactive dashboards that clients can explore in real time, as well as generate automated PDF or Excel reports they can download without my intervention. For the consultancy arm, I want a polished area that highlights past client testimonials and lets prospects book an appointment directly into my calendar (Google Calendar or Outlook integration is fine). A clean, modern front-end with mobile-first design is important, and the back-end should make it simple for me to upload new datasets, create additional dashboard views, and update testimonial content without touching code. If you prefer to build in WordPress, Django, or an...

I’m building an engagement-driven marketplace that feels as easy and addictive as scrolling through Twitter, yet fully focused on buying and selling. The core of the product is a real-time social feed where every post represents an item for sale. Users will be able to list handmade goods, digital products, and second-hand items—essentially anything they wish to move—then have those listings surface in a chronological feed that other users can like, comment on, repost, or purchase from directly. I need a full Android app and a responsive web experience that stay visually in sync and share one backend. Speed and fluidity matter; the feed should refresh instantly, images should lazy-load smoothly, and notifications should land in real time. Think infinite scroll, hashtag or...
I run an IT asset disposition, reverse-logistics, electronics remarketing, and recycling operation and I need a single web-based application that keeps every device visible from the moment we collect it until it leaves our doors. The core of the build is asset tracking and management with two must-have capabilities: • Real-time location tracking – the system should update each item’s status and physical position as soon as it is scanned or moved, whether that’s during pick-up, in-transit, inside our processing areas, or on the way to resale or recycling. • Robust inventory management – dashboards that show quantities by customer, condition, lot, and warehouse zone, plus fast search and filter tools so our team can locate any serial number in seconds. ...
I’m ready to build a marketing-driven mobile application that works seamlessly on both iOS and Android. The core experience revolves around a robust booking calendar where users can register or log in, view available slots, and lock in appointments. To help each service stand out, providers must be able to upload a short thumbnail video that plays smoothly inside the app, giving prospects a quick preview before they commit. Key flow • Secure user registration and social login • Calendar-based booking with real-time availability • Thumbnail video upload, storage, and in-app playback Essential integrations • Payment gateway (Stripe, PayPal, or similar) so clients can pay at checkout • Two-way sync with external calendars like Google or Outlook to pr...

I’m expanding our ecommerce payment system thata operates on our owned gateway and for a third party processor using one external gateway. The work is limited to the web platform and python backend; no mobile-app code is involved.

I need an experienced developer to create a Clover-marketplace app that brings full payroll capability—sourced from our UKG system—directly to merchants’ Clover dashboards. The goal is simple: let store owners run payroll without leaving their point-of-sale while keeping everything in sync across iOS and Android devices. Core features I must see at launch: • Accurate time-tracking pulled from Clover employee clock-ins • Seamless direct-deposit processing through the UKG APIs • Automated tax calculation and filings compliant with U.S. federal and state rules The build will rely on Clover’s REST/Android SDK, the UKG Ready (or Pro) payroll API, and a shared codebase (React Native or Flutter is welcome) so the same feature set ships on both pla...
I’m setting up a sleek, mobile-friendly Discord marketplace that lets members trade both digital and physical items in real time. The server needs to feel modern and trustworthy from the very first click, with a clear channel layout that guides users straight to Buy, Sell, and Vouch areas while keeping staff-only spaces out of sight. Key deliverables • Escrow system that keeps funds secure until both parties confirm the deal • Robust verification workflow so buyers and sellers earn a visible “Verified” badge before they trade • Support-ticket system that opens private threads for any dispute or question Beyond these essentials, the build should include: – Custom role and permission architecture (I’ll supply the exact hierarchy once we ...
I’m putting together an end-to-end payroll platform that lives on the web and pairs with a dedicated Android time-tracking app. The goal is a seamless flow of attendance data straight into payroll so every payslip is accurate the moment it is generated. On the payroll side I absolutely need automated salary calculation, built-in tax filing, and benefits management. Those core functions should draw directly from the attendance module to eliminate manual entry and reduce errors. For attendance, the Android app must capture reliable Clock-in/Clock-out data (with offline buffering if the connection drops), calculate overtime in real time, and feed Leave management back to the web dashboard so balances stay up to date. Key deliverables • Responsive web portal with admin and em...

I already run a WhatsApp Business account, but it still shows as “unverified.” I need someone who knows the Meta Business Manager flow inside-out to walk me through the remaining steps, review the documents I have prepared, and make sure the green checkmark appears without delays or rejections. Right after the verification is complete, I want the WhatsApp Cloud/API environment configured so I can launch fully automated messaging from our server. That includes generating the API keys, linking the number, setting an initial webhook, and proving that a sample template message can be sent successfully. Please have prior, hands-on experience with recent Meta/WhatsApp policy changes; I don’t want to waste requests or hit rate limits while testing. If you can finish both pie...
I’m building a computer-vision layer that can reliably recognise images and return structured results that the rest of my platform can consume. The core of the project is an AI-driven image-recognition model; I need someone who can take it from dataset preparation all the way to a callable endpoint. Here’s what success looks like for me: • A well-architected model (TensorFlow, PyTorch or comparable) trained on the dataset I’ll supply—or augmented with open-source sets you recommend—to reach an agreed accuracy threshold. • Clean, readable Python code with clear comments and a short README so future team members can retrain or fine-tune the model. • A lightweight API or Dockerised service that I can spin up on AWS/GCP and hit with a POST requ...

My Squareup Hosted Checkout keeps throwing authentication errors and I’m convinced the trouble sits inside the payment-method settings of my panel. I need a fresh pair of eyes to confirm that the correct Client ID and Client Secret from my Square developer dashboard are in place, that the environment (sandbox vs. production) is set properly, and that any required redirect or webhook URLs match what Square expects. You’ll log in, trace the credential flow, adjust anything that’s off, then run a quick test transaction so I can see a clean “approved” response instead of the current auth failure. A short hand-off note explaining what was changed will wrap it up. If you know your way around Squareup APIs, OAuth flows, and hosted checkout settings, this should...

I want our “Weekly Specials” process to run itself from now on. Your automation should connect directly to our WooCommerce store, pull data every week, and pick roughly ten items based on sales performance measured by revenue generated. I still may add other rules later—stock level or category—so please build the logic in a way that lets me switch criteria on or off without touching code. Once the items are chosen, the system must: • Apply the correct discount and schedule it to go live automatically. • Refresh the dedicated Weekly Specials page with pricing, images, and AI-written product blurbs. • (Optional but preferred) spin up matching social media captions and an email promo so my team can approve and send in minutes.

Core expectations • Native Android build (Java or Kotlin) with modern UI components that feel familiar to regular Play Store users. • Secure email / social sign-up and login, plus a lightweight admin view so I can verify and approve new profile submissions. • Cloud back-end of your choice—Firebase, Supabase, or a small custom A...
I need a developer who can create a reliable bridge between the Check24 platform and Hostaway. The sole focus is data synchronization—no payment processing or additional booking management logic for now. Scope • Pull new and updated booking data plus related customer records from Check24 and push them to Hostaway, and vice-versa where applicable. • Run the sync every minute with solid queue or webhook logic so neither side is overloaded. • Map all relevant fields (guest details, reservation status, dates, channel references, etc.) and handle edge cases such as cancellations or modified stays. • Build clear error handling, retry logic, and concise logging so I can audit what was sent and when. • Deliver concise setup instructions along with commented ...
I’m building a complete patient-scheduling platform that works both as a responsive website and as a companion mobile app. The core goal is simple yet critical: let patients book, reschedule, and cancel appointments in real time while giving staff a clean dashboard to manage the clinic’s calendar.

Here’s what I need from you: • End-to-end development, front- and back-end, for a secure scheduling module that plugs into our existing practice workflow. • A web interface first, with the codebase structured so we can release native iOS/Android versions without rewriting business logic. • Clean REST/GraphQL ...
I’m ready to bring a new social-networking experience to Android and need a developer who can take the idea from concept to a polished APK on Google Play. The goal is a smooth, modern interface that lets users create profiles, connect in real time, and share content easily.

If you’re comfortable working with Kotlin or Java, Firebase or a comparable cloud back end, real-time messaging, push notifications, and secure user authentication, we’ll be on the same wavelength. Deliverables I’ll review for acceptance: • Interactive Figma or XML mock-ups for sign-off • Functioning Android app (API 28+) with key social features live on a ...
I’m building an AI-driven marketplace so homeowners can instantly connect with verified plumbers, cleaners, and other home-service professionals. The first release focuses on that core matchmaking flow—finding the right provider, fast—while keeping the door open for future add-ons such as real-time chat, KYC verification, or integrated payments. Tech stack is fixed: • React Native for the iOS/Android app • Node.js API with MongoDB Atlas • Browser-based admin panel for user, job, and dispute management We are looking for an experienced full-stack development team or individual to build a production-ready AI-powered Reverse Service Marketplace for the Indian market. Unlike traditional service marketplace apps, users will post their ser...
I’m launching an online business directory that does more than list companies—it has to actively connect businesses with customers through intuitive search, rich profiles, and transparent user-generated reviews and ratings. Alongside the directory, I also need a seamless portal that supports a full multi-level marketing workflow, including easy user sign-up and management, accurate commission tracking, and clear sales-reporting tools that I can filter by date, team, or product. The finished site must look polished on any device, load quickly, and be simple for my non-technical team to maintain. You’re free to build with WordPress, Laravel, React, or another modern stack you trust, as long as the code is clean and well-documented. Security, GDPR-friendly data handling, an...
