PROFILE

I’m a senior fullstack software engineer with 18+ years building and operating scalable, reliable web platforms in Ruby on Rails and React. My experience spans the full lifecycle — system architecture, API design, cloud-native infrastructure on AWS, and the Site Reliability practices that keep high-traffic products healthy in production. I’ve led legacy-to-cloud modernizations, mentored engineers, and shipped in distributed, multicultural US/Brazil teams.

Outside of work, I’m a lifelong learner and creative spirit who enjoys music and impersonation.
