What I'm looking for

I’m looking for a team where I can build high-performance web products with React/Next.js, apply clean architecture, and keep improving through code reviews and mentoring—while owning real features end to end.

I’m a Full-Stack JavaScript Developer with commercial experience building scalable web applications using React, Next.js, and Node.js. I focus on performance, clean architecture, and maintainable code, and I enjoy working on systems that feel fast and reliable for users.

In my recent roles, I designed and implemented scalable frontend and backend architecture using Next.js and Node.js. I optimized accessibility performance with lazy loading, code splitting, and caching, and I contributed to key technical decisions while mentoring junior developers.

I also deliver strong product outcomes by integrating complex REST APIs, managing global state with Redux and Zustand, and improving SEO and page speed (including JWT-based flows). From full-stack features with MongoDB/PostgreSQL and Docker to responsive UI work with reusable components, I collaborate closely with designers and product teams to ship maintainable solutions.
