United KingdomWhat I'm looking for
I am a frontend developer with hands-on experience migrating legacy Angular apps to React, building reusable component libraries, and delivering high-impact production projects under tight deadlines. My work has improved performance, UI/UX, and driven measurable business results.
I have delivered cross-platform React Native solutions, transitioned codebases from JavaScript to TypeScript, and optimized apps for responsiveness across devices including mobile, smart TVs, and web. I also tutor aspiring developers in JavaScript, Node.js, and modern frontend/backend frameworks.
I prioritize maintainable code, developer productivity, and collaboration—using tools like Storybook, Jest, OpenLayers, and Figma—to accelerate delivery and reduce bugs while aligning implementations with product goals.
