With 15+ years of software engineering experience, I specialize in Java Spring Boot, Python, FastAPI, LangChain, LlamaIndex, PostgreSQL, Redis, vector databases, REST APIs, and cloud-ready backend architecture.
I can help you with:

My goal is to build systems that are clean, fast, secure, and easy to maintain. I focus on practical business results, clear communication, and strong technical ownership from planning to delivery.
