Part-Time Python/React Developer — Ongoing Collaboration (Hourly) Available immediately

@neerajdhameliya

Hello, I’m available to start immediately. You have a live FastAPI + React system, and the focus now is stabilizing and improving it without breaking working flows, that’s exactly where I can help. I’ve worked with FastAPI, PostgreSQL, webhooks, and payment integrations, and I’m comfortable cleaning up technical debt incrementally. I can handle webhook parsing issues, improve architecture (Pydantic + DB structure), test Mollie flows end-to-end, and fix bugs with proper guards and logging. I’m also used to PR-based workflows and collaborating with AI-assisted founders, so communication and structure won’t be a problem. Question: Which issue is currently most critical for your operations? Best, Niral

@gunslinger

That’s exactly how I usually work. With the expertise I have and exceptional client review that you can see in my profile I ensure you I can do this. I’ve been building and maintaining production systems with FastAPI and PostgreSQL, including webhook heavy flows, payment integrations, and event driven email systems, so issues like partial payload parsing, trigger reliability, and architecture cleanup are very familiar territory for me. What stood out is your current phase which is stabilizing a live system while reducing technical debt without over engineering. I can step in to clean up the architecture (layered structure, centralized DB access, proper Pydantic usage), fix webhook inconsistencies, and improve observability so things don’t silently break again. I’m also comfortable working async, proposing changes before execution, and collaborating with non technical founders who are hands on. I’m available part time and can align with your workflow (GitHub PRs, Linear, structured handoffs). My rate is €36–€45/hour depending on scope, and I can start immediately. Let’s get your system stable and scalable without slowing you down.

@Herculesz

Hi Working on a live FastAPI + React platform like this is less about adding features and more about stabilizing flows, reducing technical debt, and making the system predictable under real usage. I can support you as a senior developer focusing on backend structure (FastAPI, PostgreSQL, Pydantic), webhook reliability, payment flow validation, and frontend consistency improvements. My experience includes production SaaS systems, API design, async workflows, webhook handling, and working in AI-assisted environments where structure and discipline are critical. A common issue in AI-driven codebases is gradual architectural drift—duplicate logic, weak data validation, and fragile integrations—which leads to hidden bugs and instability. I address this by introducing clear layering, centralized data access, strict schema validation, and controlled refactoring through PR-based workflows. I’m comfortable working in your setup (Linear, GitHub PRs, async communication) and aligning with your “proposal before execution” approach. The goal is to stabilize the system, improve maintainability, and help you scale confidently without over-engineering. Thanks, Hercules

@DeyaaAhmed

Hi, I am a senior Python developer with deep expertise in FastAPI, Django & Django Rest Framework, PostgreSQL, and React, and I am specifically looking for a long-term role where I can provide the human oversight needed to stabilize an AI-assisted codebase. I understand the unique challenges of working with Cursor and AI-generated code; my approach is to respect your existing architecture while systematically refactoring technical debt, fixing the webhook mapping issues, and implementing the layered structure and Pydantic schemas you need for scalability. I will work strictly via GitHub PRs with clear proposals before execution, ensuring no direct pushes to main and maintaining the integrity of your live platform. I can immediately tackle your priority list: resolving the email trigger dashboard logic, securing the Mollie payment flow with end-to-end tests, fixing the cancelled order mail guards, and guiding the migration to TypeScript on the frontend. My goal is to be the reliable engineering partner who catches what AI misses, ensuring your platform remains robust as it grows. I am comfortable with async communication, Linear issue tracking, and your structured workflow. I'd love to hop on a call to discuss your current backlog and how we can start clearing these priorities efficiently. Let's discuss the project in more details.

@Mobilehead

Hello I once ran into a stubborn webhook mapping problem where inconsistent payload shapes broke order processing, and after adding a layered parser, strict Pydantic schemas, tests, and safe retries the bug was fixed. I understand you need webhook field mapping fixed, an email trigger dashboard with per-trigger on/off, a layered backend with a centralized DB module and Pydantic models, React state refresh and TypeScript work, an activity log per order, Mollie payment flow testing, and a set of bug fixes. I will always propose changes before coding, work via GitHub PRs with branch protection, track tasks in Linear, and keep async, structured handoffs while respecting the existing architecture and avoiding over-engineering. I am available immediately for hourly, long-term work, have deep FastAPI and PostgreSQL experience, can help on React, and am comfortable working alongside an AI-assisted, hands-on owner.
