About me
I’m a Full-Stack Web Developer specialising in React and Next.js applications. I focus on debugging and fixing issues in existing web apps, especially frontend bugs, API integration problems, and unexpected behaviour.
My recent work includes React/Next.js apps, custom CRMs, backend integrations (Node.js/AWS), and complex UI systems.
I enjoy solving difficult bugs, identifying root causes, and delivering clean, reliable fixes without breaking existing functionality.
