I'm a senior software engineer with more than 10 years of experience building production backend systems, full-stack applications, and AI-powered products. I specialize in Java, Spring Boot, Python, FastAPI, Typescript, RAG, semantic search, recommendation systems, APIs, and distributed architectures. Throughout my career, I've improved retrieval accuracy, reduced LLM processing costs, optimized application performance, and built reliable systems for high-volume workloads. What sets me apart is my ability to combine established software engineering practices with modern AI. I focus on turning promising ideas into secure, observable, and maintainable production solutions - not just prototypes. I'm looking for a fully remote Software Engineer, Backend Engineer, Full Stack Engineer, or AI/LLM Engineer position where I can take ownership, solve meaningful technical problems, and contribute to a collaborative global team.
