The engineer
behind the code

Started shipping code professionally at 18. Built and maintained production systems across the stack — databases to React UIs — and eventually led an engineering team of 15 engineers.

Did a contract stint at Johnson & Johnson (Fortune 50), working on enterprise-grade frontend at scale — 22,000+ users, strict compliance and deployment protocols.

Now intentionally specializing in AI Application Engineering— not because it's trendy, but because it's where the most interesting engineering problems live. Going deep on LLMs, RAG pipelines, agent architectures, and evals. Building real things, not following tutorials.
