Profile Description

Is your Node.js API failing, webhook not firing, or Supabase/Stripe integration breaking?
I help startups and small teams diagnose backend bugs, failed API requests, auth issues, slow queries, and broken third-party integrations without unnecessary complexity.
I can help with:

* Broken Node.js / Express APIs
* Failed webhooks
* Supabase and Firebase issues
* Stripe integration bugs
* REST API integration problems
* Auth/session issues
* PostgreSQL, Supabase, and MySQL issues
* Slow queries and inconsistent data
* Basic backend deployment/configuration issues

How I work:

1. Review the issue, logs, and expected behavior
2. Reproduce or isolate the bug
3. Identify the root cause
4. Fix the issue safely
5. Explain what changed

Recent work:

* Built a SaaS-style cash flow app with authentication, database models, and projection logic
* Built an AI-powered weight-loss coaching app with onboarding, AI-generated plan flow, and personalized guidance
* Implemented backend workflows using Supabase and API integrations
* Fixed data consistency, performance, and reliability issues in real app workflows
* Integrated AI/API features into app experiences

If your backend is failing, your webhook is not firing, or your API integration is broken, send me the details and I’ll help you diagnose the issue.
