About this gig

Is your Node.js app throwing errors, are Stripe payments failing, or does your site no longer start? I will find the cause and fix it.


What I can fix:

- Server and API errors (Node.js, Express)

- Stripe payments or webhooks not working

- Supabase database issues (queries, authentication)

- Deployment errors on Render

- Small front-end bugs (HTML, CSS, JavaScript)


How I work:

1. You send me the problem and access to your code (GitHub preferred)

2. I reproduce the bug and find the root cause

3. I fix it and explain what was changed


This service covers targeted bugs, not a full project rebuild.


Please message me before ordering so I can confirm I can solve your issue.
