Already have a Next.js and Supabase app that’s buggy, slow, or only half-finished? I’ll review your code, fix what’s broken, and clean up what’s holding it back, so you can keep building or put it in front of users with more confidence.

I work with Next.js, TypeScript, Tailwind, and Supabase (auth, Postgres database, row-level security, and storage). I start with a code review to find the real problems, send you a prioritized list, and then fix the issues we agree on. You’ll know what’s wrong and why before any work begins.

Send me a link to your repo and a short note on what’s going wrong, and I’ll tell you whether I can help.

Code review and report A review of your codebase covering structure, bugs, security gaps, and performance problems, with issues ranked by impact.

Bug fixing Fixes for broken features, errors, and unexpected behavior, including Supabase auth issues, failing queries, and RLS policy errors.

Supabase auth, database and RLS review Your auth flow, schema, queries, and row-level security policies checked for mistakes and security gaps.

Performance optimization Faster page loads, fewer unnecessary re-renders, better data fetching, and image and bundle size improvements.

UI polish Responsive layout fixes, spacing and consistency cleanup, and better loading and error states.

Deployment fixes Help with build errors and environment variable issues on Vercel, Netlify, Render, or your platform of choice.
