What I'm looking for

I’m looking for a team where I can build production-grade Python/LLM backend services—design clean APIs, run rigorous evals with pytest, tune performance, and ship reliably in Agile with strong engineering standards.

I’m a Senior Python Developer and LLM Engineer with 5+ years of experience building production-grade backend systems, REST APIs, and AI-powered applications. At Turing, I’m currently engineering LLM training and evaluation tooling, combining reliability-focused testing with practical, high-impact delivery.

I’ve architected 5+ Django applications across e-commerce, fintech, and AI domains, optimizing database performance by up to 84% and improving API response times dramatically. I’ve built systems that serve 15K+ daily active users, delivered performance from 2.5s down to 400ms, and reduced production bugs by 60% through disciplined pytest coverage.

I’m energized by scalable architecture, microservices, and LLM pipeline quality—especially LangChain/RAG workflows, vector database integration, and prompt/evaluation design. I’ve mentored cross-functional teams of 6–9 engineers and led monolith-to-microservices migrations that increased deployment frequency by 3x while maintaining high client satisfaction.
