About

Over the last 14 years, I've been building frontend applications that are fast, reliable, and easy to maintain. I am a Senior Frontend Engineer working primarily with React, Vue.js, TypeScript, Next.js, and Nuxt.js. I enjoy solving complex UI problems, improving performance, and building scalable frontend architectures that help teams deliver better products faster. Throughout my career, I've: • Led legacy-to-modern frontend migrations without disrupting production systems. • Improved application performance by focusing on real user experience, Core Web Vitals, and efficient rendering. • Built reusable component libraries and frontend architectures that reduce duplication and make development easier. • Mentored engineers, reviewed code, and helped teams adopt clean, maintainable frontend practices. I care about writing code that is easy to understand, accessible, and built to last. Great software isn't just about adding features. It's about building systems that teams can confidently maintain and evolve over time. I am currently expanding my expertise in frontend system design, performance engineering, Node.js, and backend development because building great products requires understanding the entire system, not just the UI. I am always happy to connect with engineers, product teams, and companies working on interesting technical challenges.
