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

Job ID: 40327531

Budget: €36 – €0 EUR

About the Project
We run a live, production web platform that handles end-to-end operations for a service intermediary business — connecting clients to service providers, managing order flows, automated communication, invoicing, and partner management. The platform is actively used and growing.

The Stack

Backend: Python 3.13 / FastAPI, deployed on Railway
Frontend: React + Vite + Tailwind (separate Railway service)
Database: PostgreSQL (Railway)
Integrations: Gmail API (OAuth2), Mollie payments, Gravity Forms webhooks, Sentry, GitHub Actions CI
Tools: Cursor (AI-assisted development), GitHub (branch protection, PRs)


Current Status
The platform is live and operational. Core flows are working — quote management, order confirmation, partner portal, automated email triggers, invoicing with payment links. We are in a stabilization and feature completion phase. The codebase is functional but has technical debt that needs structured attention.

What Needs Work
Current open priorities include:

Webhook field mapping issues (incoming data not fully parsed)
Email trigger dashboard — visibility and on/off control per trigger
Code architecture improvements (layered structure, centralized DB module, Pydantic schemas)
React frontend improvements (state refresh, TypeScript migration)
Activity log per order
Mollie payment flow end-to-end testing
Bug fixes: cancelled order mail guards, partner mail routing


About Me
I'm a non-technical founder working hands-on with AI-assisted development (Cursor + Claude). I have a good understanding of the system and try to stay actively involved in decisions. My goal is to work structured — proposal before execution, no direct pushes to main — but in practice I run into the limitations of AI-driven development regularly. That's part of why I'm looking for a developer: to add human oversight, catch what the AI misses, and help keep the codebase from drifting.

What I'm Looking For
A senior developer comfortable working alongside an AI-assisted owner. You don't need to hand-hold me, but you do need to:

Work on an hourly basis, long-term
Communicate clearly before making changes
Respect the existing architecture and not over-engineer
Be comfortable with a mixed AI/human workflow
FastAPI + PostgreSQL experience required; React experience a plus


Collaboration Style

Issues tracked in Linear
All work via GitHub PRs
Async communication, structured handoffs
Proposal before execution — always

If you like working on a real, live product with a hands-on owner who knows what he wants — let's talk.
