Sobre este Serviço

Broken build? A 500 error you cannot trace? A feature that worked yesterday and not today? I fix it, fast, at the root, without breaking the rest of your app.


I am a senior engineer with 500+ orders, 100% satisfaction and 8,700+ hours on production apps. I debug React, Next.js, Node, Express, TypeScript and Python across frontend, backend and full stack. Not a band-aid that breaks next week: I find the root cause, fix it cleanly, and explain in plain English what was wrong.


What you get:

- Root-cause fix, not a symptom patch

- Clean commit or patch on your repo, so you own everything

- A Loom walkthrough (Standard and Premium) so you understand the fix

- A regression check (Standard and Premium) so nothing else breaks


Recently: fixed a production 500 error and installed Sentry cleanly for a US client (see reviews). I work fast and I am honest. If I cannot reproduce it, you do not pay.


Not sure which package fits? Send me what you have and I will honestly tell you which tier you actually need.

    Hasham delivered both items from the original order — fixed the /api/admin/logs 500 error and installed the Sentry SDK cleanly. When his first deploy surfaced a separate pre-existing issue with our production database, he investigated quickly, owned the gap in his local testing approach, and walked me...
