Über mich
Senior Full-Stack Engineer with 15+ years shipping production web and mobile apps for marketplaces (OLX, dubizzle), B2B platforms, and fintech. I build with React, Next.js, TypeScript, Node.js, PostgreSQL and AWS, and I started as a UI designer, so the interfaces I ship look right as well as work right. Recent results: 30% faster Time-to-Interactive after an SSR migration, 40% fewer production defects after introducing TDD, a zero-downtime React 19 upgrade across 250+ files. I also founded a live iOS/Android SaaS end-to-end. Clear communication, clean code, on time.
