About

Software engineer with 8+ years shipping mobile, frontend, and backend systems across logistics, travel, and EdTech.

I care less about shipping features and more about understanding what's actually slowing users down — the gap between what people say they want and what they need. That's the lens I bring to every product I build.

Most recently, I've been building AI workflows for a staffing platform: an AI recruiter that interviews and processes ~3,000 candidates a month, and an AI supervisor that monitors 1,000+ active jobs a day, catching risk (stalled progress, missing requirements, bench issues) before it becomes a real problem. Working with prompt engineering, RAG, and embeddings has become a core part of how I build now, and I'm continuing to lean further into AI-powered systems.

Along the way I've launched apps from scratch, scaled products to millions of users, led architecture decisions that became the foundation for large parts of an org's codebase, and mentored other engineers.

Based in the New York metro area. Fluent in English and Spanish.
