I build production-ready backends that are fast, secure, and easy to maintain. My core stack is Python/FastAPI + PostgreSQL (SQLAlchemy, Alembic, JSONB) with JWT auth, Pydantic validation, background tasks, and clear, testable code. I’m database-first: I design schemas, craft composite/covering indexes, optimize queries, and enforce idempotency with safe upserts and strict error handling.
Recently, I shipped ForeverBook, an AI storytelling platform: JWT-secured APIs, age-gated content, instant listing endpoints, per-user read history, and resilient LLM integrations (OpenAI) with strict-JSON parsing and multi-step fallbacks. I also contribute ML utilities when needed and can interoperate in C++/.NET/C#.
What I deliver
Clean REST APIs with predictable contracts and docs (OpenAPI/Swagger)
Solid DB design (JSONB, indexing, migrations) and performance tuning
Robust integrations with OpenAI/LLMs, background workers, and retries
Maintainable code: typing, tests, logging, and readable error payloads
