I build Python and FastAPI backend services for AI products, workflow systems and external integrations. This work can include REST APIs, webhook receivers, structured data validation, provider integrations, calendar/CRM actions, error handling and testable business logic.
This service is for founders and teams that already know the product outcome but need the backend layer to be reliable. I am comfortable working with API documentation, JSON payloads, repositories and milestone-based delivery. Relevant work includes a FastAPI booking service that receives structured call data, validates it and creates real calendar events.
A small first scope can be: one API endpoint or webhook integration, validation, a documented response format, test cases and a concise handover. For a bigger product, I break work into discovery, architecture, build and integration milestones.
Send the existing stack, provider/API documentation, expected input/output and acceptance criteria. I will identify the smallest useful build.
