I will build backend apis with python fastapi or nodejs

Need a specific backend feature implemented cleanly in your existing application? I build one agreed API endpoint using Python/FastAPI or Node.js, with clear inputs, outputs and error handling.

My portfolio includes WaveForm, which connects capture, cloud upload and 3D reconstruction; MyLeadBots, a lead-research pipeline; and ClipForge, a video-processing product using FastAPI and background jobs.

For $150, I will implement one bounded endpoint in 5 days with 1 revision. Delivery includes request validation, agreed tests, endpoint documentation, source code and local setup notes.

Send the required behavior, sample request/response, existing code and relevant API documentation before ordering. We will agree acceptance checks and the implementation boundary first.

The starter price does not include a new authentication system, database redesign, migration, payment integration, frontend or live deployment. External integrations and larger features require a separate scope. No unlimited capacity or security certification is promised.
