CS student in China building Python backends and reliable AI application infrastructure. I build tested APIs, database-backed workflows, background-processing systems, and controlled AI integrations.
- Backend: Python, FastAPI, Pydantic, SQLAlchemy, Alembic
- Data and jobs: PostgreSQL, SQLite, Redis, RQ, Pandas
- Quality and delivery: pytest, Git, Linux, Docker, REST/OpenAPI
- Supporting UI: React, TypeScript, Streamlit, HTML/CSS
- AI applications: external model APIs, structured outputs, persistence, fallbacks, and evaluation cases
- Build or extend a tested FastAPI feature or REST API
- Add authentication, permissions, database models, and migrations
- Implement background jobs and document/media-processing workflows
- Integrate an external or LLM API with validation and failure handling
- Add API regression tests and improve backend reliability
