I will fix nextjs react and supabase bugs
Danila Titovets
About this gig
Is your Next.js, React, or Supabase application showing errors, broken pages, authentication problems, or failed API requests? I will investigate the root cause and deliver a clean, tested fix.
I can help with:
Next.js and React UI or runtime bugs
Supabase authentication, sessions, database queries, and RLS policies
API integration and server-side errors
TypeScript, build, deployment, and environment issues
Performance problems caused by code or database requests
My workflow:
- Reproduce and investigate the issue
- Identify the root cause
- Implement the agreed fix
- Test the affected user flow
- Provide a clear summary of what was changed
I work with real SaaS platforms, CRM systems, dashboards, booking services, Telegram bots, payment flows, and business automation tools.
Please message me before ordering with a short issue description, screenshots or error logs, your technology stack, and the expected result. I will confirm the scope and recommend the correct package.
This Gig covers bug fixing. New features, redesigns, and major architecture changes require a custom offer.

FAQ
What information do you need to start?
Please send a description of the issue, steps to reproduce it, screenshots or error logs, your technology stack, and the expected result. Repository or staging access may be requested after the scope is confirmed.
What counts as one bug?
One bug is one reproducible issue with a single root cause. If several problems have different causes, they count as separate bugs.
Can you fix Supabase authentication and RLS issues?
Yes. I can investigate authentication, sessions, database queries, permissions, and Row Level Security policies in Supabase applications.
Can you fix deployment and build errors?
Yes. I can troubleshoot Next.js, Node.js, Vercel, environment variable, TypeScript, build, and deployment issues when they are included in the agreed scope.
Should I contact you before ordering?
Yes. Please message me first so I can review the issue, confirm that it is reproducible, and recommend the correct package before you place an order.
