About

Turning real requirements into systems that ship.

Senior Software Engineer and Engineering Leader with strong experience designing and building production systems across AI, data, and cloud platforms. Solid background in backend development (Python, Node.js, Go), system design, and full-stack engineering — building scalable, reliable services from idea to production.

Hands-on with applied AI: semantic search, RAG pipelines, real-time systems, and speech technologies, alongside traditional data-driven architectures. I work closely with stakeholders, turn real requirements into practical solutions, and take full ownership of systems in fast-moving environments.
