About this gig

I'm a full-stack developer specialising in React and Next.js applications, helping fix bugs, debug issues, and stabilise production systems quickly and reliably.


If your website or app is broken, behaving unexpectedly, or you're stuck on a frontend or integration issue I can help identify the root cause and fix it cleanly.


I have worked on production systems including:

  • React / Next.js applications
  • API integrations and backend services (Node.js / AWS)
  • Complex UI systems (including 3D and interactive frontends)
  • CRM-style internal tools and dashboards
  • Business landing pages


What I can help with:

  • React state and UI bugs
  • Next.js routing, SSR, hydration issues
  • API / backend integration issues
  • Broken components or unexpected behaviour
  • Performance or rendering issues
  • General debugging and code fixes

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.
