About
Who I Am
I build applications where AI does real work — not demos, not wrappers. Language models, retrieval-augmented generation, and agentic workflows, wired into production systems with Next.js, TypeScript, and PostgreSQL.
My path into software started outside of it. That non-traditional background gives me a bias toward shipping things people actually use over chasing architectural elegance for its own sake.
Right now I'm deep in context engineering and agentic AI — figuring out how to make LLMs reliable enough to trust with consequential tasks.
