Need an API to ingest, validate, transform, and serve your data reliably?
Im a Data Engineer and I build production-ready data processing APIs using Python + FastAPI (with clean architecture, tests, and documentation).
What I can build
- REST API for data ingestion (CSV/JSON/Parquet)
- ETL endpoints (cleaning, transformation, enrichment)
- File conversion APIs (CSV Parquet, JSON CSV, etc.)
- Integration with PostgreSQL / MySQL / BigQuery
- Async/background processing (Celery/RQ optional)
- Auth (API key / JWT), rate limiting, logging
- Docker-ready deployment
What you get
- Clean, documented API (OpenAPI/Swagger)
- Robust input validation + error handling
- Unit tests (optional in packages)
- Dockerfile + deployment guidance
- Clear handover + usage examples (curl / Postman)
Business use-cases welcome: reporting pipelines, KPI APIs, automation, internal tools, microservices.
