ASP.NET Core / Razor Developer & Technical QA Partner — Paid Trial, Long-Term Opportunity I run a small software business building custom operational software for SMEs. My role is primarily focused on: - finding and communicating with clients; - understanding how their businesses currently operate; - identifying operational problems; - designing the solution and defining requirements; - prioritizing features; - managing the client relationship; - reviewing and approving the final product. I am looking for a developer who can take ownership of the technical execution of those solutions. This is initially a small paid trial, but I am genuinely looking for someone I can work with repeatedly over the long term. If we work well together, I would prefer to build a stable relation...

I need a seasoned full-stack developer to take an AI-first web application from concept to production. The product will streamline document and form handling for both internal staff and end-users, so scalability, security, and clean UX are critical. The stack I have in mind is WeWeb or FlutterFlow for the front end paired with Supabase/PostgreSQL on the back end.

The system will connect a CRM/API with a Python backend and an AI layer to automate selected customer and lead-management workflows.

I want to extend my current Odoo environment with a tailor-made Sales Management module. This is not a vanilla install or a bit of configuration—I need full custom module development that plugs cleanly into the existing stack and follows Odoo best-practice coding standards (Python, XML views, qWeb, ORM). Core scope • Quotation Management – streamlined quotation creation, versioning, and automatic status tracking. • Sales Reporting – dynamic dashboards and exportable reports that slice by product, salesperson, and period. • Customer Relationship Management – lightweight CRM touches tied directly to the new sales workflow so every interaction is logged and searchable.

I am looking for an experienced Full Stack Developer to review, improve, optimize, and enhance an enterprise-grade ISP Customer Relationship Management (CRM) and ticketing platform. SuperLink ISP CRM is designed to manage ISP operations from a centralized platform, including customers, sites, network connections, tickets, billing, payments, credentials, quotations, and operational workflows.

I’m looking for an experienced full-stack developer to help me finish and professionally stabilize an existing SaaS product called Neirom. Neirom is already largely built and live. This is not a project starting from zero, and I do not want a complete rebuild. I need someone who can review the existing codebase, understand what is already working, fix the remaining problems, improve performance and reliability, and bring the product to a professional production-ready standard. Current Stack / Integrations Include: - React / TypeScript - Supabase / PostgreSQL - Lovable - Anthropic AI API - Paddle payments - Resend email - Shopify OAuth, product sync, and webhooks - Etsy OAuth/API integration - GitHub What I Need: 1. Full technical audit of the existing application. 2. Fix bugs and ...

Hi, I can build this as a compact, reliable web application focused specifically on the business workflow you want to automate, rather than overengineering it into a large platform. My preferred stack would be Python with FastAPI/Django, PostgreSQL where needed, and a lightweight browser-based frontend, with Git-based source delivery and clear deployment documentation. I have built and deployed multiple backend/API projects involving automation, background processing, databases, authentication, testing, and deployment. In particular, my AI Agent API handles automated workflows using Python, APIs, PostgreSQL, Redis, and Celery, while my SaaS and marketplace APIs demonstrate experience building maintainable web systems. I can provide: - Complete source code in Git - Working web applicati...

I have an internal dashboard that uses AI to generate automatic email replies. It works, but it’s starting to fall behind our needs. The main goal is to boost the accuracy of each suggested response while making the interface feel smoother for everyday users. Accuracy updates • Refine keyword-matching so the system chooses the right intent even in edge-case phrasing. • Incorporate stronger natural-language-processing techniques to handle varied sentence structures and tone. • Refresh or retrain the underlying data models; I’ll provide sample email logs for you to fine-tune on. Interface refinement Right now the layout is functional but clunky. I want the overall user experience to feel intuitive—fewer clicks from draft to send, clearer confidenc...

The successful developer will be responsible for taking the existing build and completing the technical/backend functionality required to make it a real working application. Scope of work The project is...

I need a solid backend written in Python that powers one-on-one messaging for an existing mobile chat application. The core tasks are to expose clean REST and WebSocket endpoints, handle real-time delivery, persist messages reliably in PostgreSQL, and keep latency low under moderate load. Authentication is already in place; your job starts at the moment the client is authorised. From there the service must: • accept text, emoji, and small attachment payloads • write each message atomically to Postgres, marking it delivered and later read • push live updates back to the correct recipient through WebSockets • expose a simple status route for health checks and basic metrics Unit tests that cover the message flow, delivery confirmations, and failure scenarios ...

We are building **R0** — the first production slice of an operational assistant used by a real, paying French client. This is not a prototype, not a redesign exercise, and not an open-ended AI product build. The architecture, product behavior, data contract and acceptance criteria are **already decided and documented**. We are buying implementation, not discovery. You will receive, before you quote: - a vendor-neutral engineering scope - a conversation contract (how the assistant must understand and speak) - an acceptance fixture pack containing **real data and expected outcomes** - the **source code of our existing PDF generation service**, which you must reuse Most of the behavioral design work is already done. Your job is to build it correctly. --- ### What the system does ...

I have a PDF that holds a little over two-hundred rows of mixed letters and numbers—think product codes, IDs, brief labels—that all need to live in a clean, well-structured Excel workbook. Your job is to lift every character exactly as it appears, place each field in its correct column, and keep the original ordering intact. The PDF is not a scan with fuzzy text; it is a digital file, so copy-and-paste or a reliable PDF-to-Excel tool such as Adobe Acrobat, Able2Extract, or even Power Query should work. Whichever method you prefer is fine as long as the final sheet is accurate and uniformly formatted—no merged cells, stray spaces, or wrapped lines that break the flow. Once finished, return an .xlsx file that I can open in Excel 2019 without prompts or compatibility w...

I have already taken Flyenzo from concept to a working end-to-end flight booking flow using 16 with the App Router, TypeScript, Neon Postgres via Drizzle ORM, Redis, Stripe, and Clerk auth. Search, Stripe Checkout, PNR generation, printable e-tickets, and online check-in are live and stable. What I need now is focused, production-ready work on three areas that matter most to travellers and to the business: 1. Live cabin map The current map renders seats and respects my Redis Lua seat-lock script, but I want smoother real-time updates across multiple sessions, optimistic UI during seat selection, and graceful fallback in local development when Redis is not available. 2. Ancillary add-ons Meal options, lounge access, and priority boarding must be selectable in-flow, priced dynamicall...

We have an existing live bilingual Saudi offers and loyalty platform built with React, TypeScript, Node.js/Express and PostgreSQL. We want to package the existing responsive web platform as one mobile application for both iOS and Android using Capacitor or a similarly suitable WebView-based approach.

The same application will serve different users according to their existing server-side roles and permissions: - Customer. - Store manager. - Branch manager. - Offer manager. - QR validation employee. - Platform administrator remains primari...

Looking for an experienced Full-Stack Developer to help finalize an almost-completed web application and make it fully launch-ready and deployment-ready. The project is already largely built and functional. I am not looking for someone to start from scratch. The main work will involve reviewing the existing codebase, checking that all frontend and backend components are properly wired together, fixing any broken flows, completing unfinished features, improving security, testing the application thoroughly, and preparing it for production launch. The developer should be comfortable with: * Reviewing an existing full-stack codebase * Checking frontend-to-backend wiring * Verifying API integrations * Fixing incomplete or broken functionality * Completing remaining features * Improving auth...

Our main database is already running on PostgreSQL 13 (anything in the “12.x or higher” family), and I need an experienced DBA to step in and tighten two things: First, Database optimization. The work includes reviewing current configuration parameters, checking execution plans, tuning indexes, and suggesting any schema changes that will noticeably reduce latency under peak load. If extensions (pg_stat_statements, auto_explain, etc.) should be enabled or configuration values (shared_buffers, work_mem, effective_cache_size and friends) adjusted, please make those recommendations backed by data. Second, Backup and recovery. I want a clear, scripted process—preferably with pg_dump and/or a modern tool such as pgBackRest or Barman—that covers daily backups, point-in-t...

I’m putting together a restaurant POS modeled closely on the Petpooja experience, and I need the backbone of the system built right away. Your task is to create clean, well-documented PHP APIs that my mobile and web teams can plug into immediately. Scope of the APIs • Core focus: real-time inventory management—stock levels, item variations, automatic deductions after each sale, low-stock alerts, and simple purchase-order generation. • Seamless sales and transaction hooks so that, when I’m ready, we can extend the same codebase to cover billing, reporting, and customer data without rewriting everything. • Secure authentication, role-based access, and clear JSON responses are mandatory so integration stays painless. • MySQL (or MariaDB) is prefe...

I have an existing Excel form that collects both text and numerical inputs. I now need that form wired to a simple web-based submission flow so users can fill it out online instead of emailing me the file. When they hit “Submit,” the collected values should be pushed directly into a back-end database for safe storage and later analysis—no other post-submission actions are required. Please build a lightweight web form that mirrors the current Excel layout, handle all field validation for mixed data types, and create the connection layer that writes each record to the database. A short hand-off guide or commented code explaining how to adjust the form fields in the future will round out the job. Key deliverables: • Responsive web form that captures every Excel field ...

Our production systems run on a dedicated PostgreSQL database server that needs ongoing, professional management to keep performance high and downtime at zero. I need an experienced PostgreSQL administrator to take charge of routine upkeep, monitoring, and rapid incident response so the team can stay focused on product development.

The server is Linux-based and accessed via SSH; fluency with psql, pgAdmin, and common monitoring stacks (Prometheus, Grafana, or similar) will make the job straightforward. Deliverables • Initial health audit ...

I need to add end-to-end payments processing to my application so that customers can complete financial transactions without ever leaving the platform. The core work involves choosing and integrating a mainstream gateway (Stripe, PayPal, Adyen or a comparable API), wiring up the server-side logic, and exposing clean client-side calls that handle tokenisation, 3-D Secure flows, refunds and recurring charges where relevant. The codebase is currently built in Node.js with a React front end, so familiarity with this stack, REST/GraphQL, and typical PCI-DSS best practices is important. I already have merchant accounts in place; what I am missing is the glue that turns an order into a confirmed, securely captured payment and stores the resulting transaction metadata in my PostgreSQL database....

I’m putting together a cross-platform billing and inventory SaaS that must run smoothly on the web (React) and mobile (Flutter). The core stack is already chosen: a Django backend with a PostgreSQL database, all deployed on AWS. Key functional blocks you’ll build and wire up: • Subscription engine – monthly recurring plans driven by Razorpay Subscriptions API, with optional Stripe fallback, automatic invoicing, proration, and dunning logic. • GST-compliant invoice management – create, edit, email, and share invoices; integrate with the GSTN e-invoicing APIs for real-time IRN and QR code generation. • Inventory & batch tracking – receive stock, monitor quantities, lot/expiry dates, and link sales orders to inventory reductions. &bul...

I have a small in-house codebase that already runs a few large-language-model helpers, but I now need to expand it with three new agents: a Sales Assistant, an Email Agent, and a Document Management Agent. All three must plug into the same Python stack (LangChain, OpenAI API, vector store, webhook layer) and respect our existing coding patterns. Here is the core scope we will iterate on together: • Sales Assistant Agent – Lead generation from incoming data feeds and web sources – Follow-up communication that can draft, personalise, and schedule messages – Basic sales analytics so my team can see pipeline health at a glance • Email Agent – Automated responses that pick the right template and tone – Sorting and categorisation i...

I have a complete, clean PostgreSQL database of a football club's entire match history — 120 years, roughly 6,900 matches, with lineups, goals, cards, players, managers, referees and venues. **The data work is finished.** I need a developer to build the website on top of it. There is a full written specification and a technical appendix documenting every table and data convention. Both go to shortlisted bidders. This is a well-defined build, not a discovery project. ### What exists already - A PostgreSQL 17 dump (~10 MB, 35 tables) that restores cleanly, with a documented schema - A working read-only reference viewer you can browse: **** - A ~15-page specification covering every page, every form, colours, and an acceptance checklist - A technical appendix covering data conven...

I need an experienced developer to carry out several coordinated upgrades on my existing e-commerce system. 1. PHP Admin Panel The product-management area must let me update existing items more intuitively. That means revising the update logic, refactoring the related PHP views/controllers, and adjusting any database calls so new fields or validations are stored reliably. 2. Flutter Mobile App Parallel to the back-end work, the customer-facing Flutter app needs UI tweaks that mirror the revised product data structure and keep the overall look consistent with our latest branding guidelines. 3. POS Integration Our in-store POS has to feed sales, stock moves, and pricing changes straight into the admin panel. A clean, real-time sync (REST or webhook—whichever fits best...

I run a busy plumbing-supply shop and need a small web portal that makes every new purchase entry worth more than a line on paper. Here is the flow I have in mind: the counter staff open the site, record the item name and quantity, note the supplier and the exact purchase cost, then hit “Save.” As soon as that happens two things must occur automatically: 1. The system stores the entry so I can search, filter or export it later. 2. A WhatsApp Business message is fired off to a pre-defined contact list—filtered by the product category we’ve tagged—letting customers or team members know fresh stock has arrived. Only the “new purchase entry” event should trigger these notifications; low-stock or scheduled reports are not required right now. I ...

Machine Learning Pipeline – Job Market Analytics & Salary Prediction Created an end-to-end machine learning pipeline for looking at job market data and guessing what salaries might be. Key Features: Worked on. Fixed 10,000 or more job-market records using Python, Pandas and NumPy. Made an automated ETL/data preprocessing pipeline to take care of data cleaning, changing data making it all the same and checking if it is all the same. Added a PostgreSQL (Neon) database to keep data in a good way and help with machine learning work. Did analysis of the data. Looked at the features to find what helps predict salary. Trained a Random Forest regression model to guess salaries. Found that employee_residence is one of the things to use for guessing salaries. Built a Fas...

This project involves building an end-to-end QR Code Parking Tag system that works seamlessly as both a responsive web application and a Telegram bot. The single most important capability right now is reliable QR-code scanning so attendants can quickly validate a vehicle’s tag from any mobile device or desktop webcam. Key expectations • One shared backend should power both the web front end and the Telegram bot, so data stays in sync. • The web app needs a clean dashboard where administrators can create and manage parking tags, monitor scans in real time, and export simple usage logs. • The Telegram bot must mirror the same scan-and-validate flow, returning an immediate success/denied message inside the chat. • Code quality and clear documentation are cru...

# Senior Full-Stack Developer - Real-Time Squash Scoring & Tournament System ## Project Overview We are a squash club in Denmark with 7 courts and regular tournaments/events. We currently have an online scoring system where referees enter scores live during matches. The basic functionality works well, but the system is unreliable, frequently goes down, and we are heavily dependent on the original developer, who is difficult to reach.
