I will fix bugs in your react node or supabase application fast
John R
About this gig
Something broken in your React, Node.js, or Supabase app? I'll diagnose and fix it fast. Failed deployments, RLS policy errors, broken API calls, React state bugs, race conditions. I've spent 5 years shipping and maintaining production apps, including as an engineering lead, so I know how to find root causes quickly, not just patch symptoms.
