What I'm looking for

I seek a collaborative team focused on building scalable, well-tested front-end systems (React/Next.js) with opportunities for technical ownership and CI/CD improvements.

I am a Front End Developer with over nine years of professional experience building modern, high-performance web applications for agencies and large platforms. I specialize in React and Next.js, and I led full rewrites and migrations to improve scalability, maintainability, and developer experience.

My achievements include redeveloping a legacy jQuery platform into a Next.js/TypeScript/Tailwind app with WebSocket real-time messaging, migrating a large Angular client area to React with Module Federation, and implementing a Kubernetes-based CI/CD pipeline to enable feature-branch deployments.

I enjoy close collaboration with product, design and engineering teams, delivering high test coverage and reliable user-facing features while working with headless CMSs, GraphQL, micro frontends and modern dev stacks.
