About

Ownership, architecture, and production impact

Senior Full Stack Software Engineer with 5+ years building software across modern web applications, B2B products and enterprise systems. I work primarily with TypeScript, React, Next.js and Supabase, complemented by SQL, APIs and backend engineering.

Today I own architecture and end-to-end product delivery at CAW Tech as Principal Software Engineer and Co-Founder. Previously I maintained and adapted banking systems at CENSYS and completed a competitive frontend internship at Globant. What differentiates my profile is the combination of modern product engineering and SaaS ownership with enterprise systems and legacy modernization — protecting transactional integrity while shipping real-world production platforms.

I look for Senior Software Engineering and Full Stack roles where technical ownership, system design and measurable business impact matter — with a path toward technical leadership and architecture.
