What I'm looking for

I seek a front-end role focusing on React/TypeScript, building reusable components, improving performance and test automation, within collaborative teams that value quality and iteration.

I am an experienced front-end developer with 6+ years building responsive, scalable web applications, specializing in the React ecosystem and modern JavaScript frameworks. I focus on creating efficient, user-friendly interfaces, reusable component libraries, and maintainable codebases that accelerate product iteration.

At RightCapital I led development on a Group Enterprise Financial Management Platform using TypeScript and React 18, implemented a Puppeteer-based PDF printing service, and built automated E2E test suites with Cypress and Playwright to cut test execution time by over 50%, improving release confidence and deliverability.
