You will get your Lovable or Supabase web app fixed and stabilized
Project details
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.

About José
Full Stack Developer | Python/Django, APIs & Automation
Santiago, Chile - 2:28 am local time
I build and improve full-stack web applications, with a strong focus on backend development, APIs, authentication, databases, integrations, and reliable production behavior.
I can help with:
* Python, Django, and Django REST Framework backends
* React, Next.js, JavaScript, and TypeScript applications
* REST APIs, webhooks, and third-party integrations
* PostgreSQL databases, authentication, and permissions
* AI-built app debugging, stabilization, and production-readiness work
* Business automation with APIs, webhooks, AI, and custom logic
* Stripe and payment integrations
* Docker, Linux, Nginx, deployment, and production troubleshooting
* New features, bug fixes, and existing codebases
I have worked on e-commerce, inventory, booking, payment, API, web, and SaaS-style systems, including products used in real production environments.
My approach is engineering-focused: understand the existing system, identify the real problem, make maintainable changes, test the affected behavior, and communicate technical risks clearly.
If you already have something partially working, I can help improve it without automatically pushing for a full rebuild. If you are starting something new, I can help design and implement the backend, frontend, APIs, integrations, and deployment needed to get it running.
Tell me what you are building, what already works, and where you are currently blocked.
