I will fix and stabilize your lovable or supabase web app
Jose Olguin L
About this gig
If your Lovable, Supabase, Bolt, Replit, or AI-built web app is partially working but has broken flows, bugs, fragile integrations, or stability issues, I can help fix and stabilize the existing application without automatically rebuilding it from scratch.
I work on clearly defined issues and app areas such as:
* Critical bugs and broken user flows
* Authentication and permission issues
* Supabase database, RLS, and data-access problems
* API and webhook failures
* Incomplete or broken features
* Third-party integration issues
* Error handling and reliability problems
* Performance and deployment-related issues
My approach focuses on understanding the root cause, making maintainable fixes, testing the affected behavior, and reducing the risk of introducing new regressions.
This service is for existing applications with an agreed scope. It does not include unlimited bug fixing, a complete application rewrite, penetration testing, or unrelated new features.
Each package covers only the issues, feature, or application area agreed within its scope. A revision covers adjustments to the delivered work and does not add new features or unrelated problems.

FAQ
Do you rebuild the entire application?
No. This service is designed to fix and stabilize an existing application. A full rebuild or major architectural rewrite requires a separate scope and estimate.
Which apps and technologies can you work with?
I can work with Lovable, Supabase, Bolt, Replit, React, Next.js, JavaScript, TypeScript, Python, APIs, databases, and third-party integrations, depending on the existing codebase and agreed scope.
What counts as a revision?
A revision adjusts the work already delivered within the agreed scope. New bugs, unrelated features, extra integrations, or newly requested functionality require a separate scope.
Can you fix Supabase authentication, RLS, or database issues?
Yes, when included in the agreed scope. I can address auth flows, permissions, RLS policies, data access, and database-related bugs. This is application hardening, not penetration testing or compliance certification.
What if you discover additional problems while working?
I will document and explain any additional issues I find. I will not expand the scope without your approval. Extra work can be handled through a separate milestone or agreed scope.
What is included in the Documentation extra?
The Documentation extra provides a structured technical handoff covering the problems addressed, relevant changes made, affected areas, important implementation or configuration notes, validation performed, known limitations, and recommended follow-up items. It is not full codebase documentation, a
