// About Me

I engineer systems
built to last.

Lead Platform Engineer with 5+ years of experience building production software and owning systems from architecture through deployment.

I specialize in backend architecture, AI systems, and secure scalable platforms, designing APIs, data models, LLM workflows, real-time systems, and production infrastructure.

My recent work focuses on AI-powered platforms where intelligent automation and human decision-making work together, including evidence intelligence, talent technology, workflow automation, and personalized AI systems.

I work with end-to-end ownership: translating business requirements into technical architecture, building the underlying systems, integrating AI safely, and taking products through deployment and iteration.
