01
Reproduce
Confirm the failing path and one measurable acceptance criterion before changing code.
Next.js · Supabase · Vercel
One production bug. A bounded fix. Evidence you can review.
I diagnose one reproducible Next.js or Supabase production failure, implement the smallest reliable correction, and verify the nearest regression path. No hidden redesign or open-ended refactor.

How the sprint works
02
Trace
Follow the issue across the relevant client, server, database and deployment layers.
03
Fix
Implement the smallest reliable correction that fits the agreed single-bug boundary.
04
Verify
Check the repaired path and its nearest regression risk, then provide handover and rollback notes.
Send useful evidence
Enough context to reproduce—without exposing production secrets.
- The exact failing URL, action, request or command and the expected result
- A minimal reproduction, relevant branch or the smallest affected code path
- Sanitized logs with timestamps and the deployment or environment involved
- Staging access or synthetic test data when the issue cannot be reproduced locally
Before you order
Production bug-fix questions
What counts as one production bug?
One reproducible failure with a bounded expected result—for example a broken Next.js route, a Vercel runtime failure, a Supabase auth or query path, or one webhook flow. Several unrelated symptoms or a feature build require a separate scope.
Is a fix guaranteed within 48 hours?
The two-day delivery window starts after usable requirements arrive. The sprint guarantees a bounded diagnosis and evidence-led work, not that every unknown system can be repaired without wider changes. If the evidence shows a larger problem, you receive that finding early instead of an unsafe patch.
Do you need production secrets or customer data?
No. Start with staging access, a reproducible example, sanitized logs and the minimum relevant code. Never send production passwords, service-role keys or real customer data in chat.
What is outside this sprint?
A redesign, new feature, broad refactor, open-ended security test, infrastructure migration and multiple unrelated bugs are outside the $249 starter scope.
Need a full Supabase authorization review?
The separate RLS audit covers exposed tables, policies and cross-user or cross-tenant access paths from $299.
