Hi there! I’m a senior full stack developer based in Santa Monica with 8+ years of experience building scalable web applications and backend services. My primary focus has been Ruby on Rails, JavaScript, and Python, and I enjoy designing robust architectures, shipping production-grade APIs, and delivering solid frontend experiences. I gravitate toward tackling hard architectural problems such as API design, frontend architecture, and end-to-end stack coherence, and I thrive both independently and in strong teams. I’ve led complex ETL pipelines, built AI-enabled data processing workflows, and continuously optimize costs and reliability at scale. I value collaboration, mentorship, and improving development processes, and I’m always learning new tech to keep shipping high-quality software.
