Senior front-end developer building high-performance React apps with JavaScript and TypeScript.
What I'm looking for
I’m a Senior Front End Developer and highly qualified Senior Full Stack Software Engineer with 15+ years of cross-functional expertise, specializing in React, JavaScript, and TypeScript. I architect and develop scalable, high-performance front-end solutions, optimizing UI responsiveness and debugging issues to keep products smooth and reliable.
In agile environments with distributed teams, I lead and mentor through code reviews, help teams align with product goals, and streamline workflows by improving CI/CD and maintaining coding standards. From building admin tools from scratch at Tesco—reaching an 80% unit test coverage rate—to cutting bundle size by 50% at Paxos using lazy loading and performance optimization, I consistently deliver measurable outcomes.
