Frontend engineer specializing in React, TypeScript, and high-performance web and mobile apps.
What I'm looking for
I am a Frontend Engineer with five years of experience building scalable web and mobile applications, focusing on React, React Native, TypeScript, and Next.js. I lead large refactors, design reusable UI systems, and deliver measurable product improvements.
At my current role I migrated a high-traffic healthcare platform to Next.js and microfrontends, launched a React Native app that reached 10k+ installs, and built a shared UI Kit that reduced delivery time by 20%. I also improved performance, accessibility, and CI/CD pipelines to drive reliability and user retention.
I enjoy solving complex engineering problems, automating manual workflows, and shipping polished user experiences. I bring a pragmatic, results-driven approach and a strong emphasis on maintainable, performant front-end architecture.
