SUMMARY
I'm a Frontend Developer specializing in React and TypeScript, with 2+ years of commercial experience. I've
worked both independently and as part of a team on projects ranging from building applications from
scratch to improving and modernizing existing systems.
I’m comfortable working across the development lifecycle, from gathering requirements from product
owners to implementing and deploying applications. I also have Full-Stack development experience, using
Node.js, Express, and NestJS to build backend components of web applications.
