Informazioni su questo servizio

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 hat meine Photoshop-Plugins wieder zum Laufen gebracht und mir damit unglaublich viel Arbeit erspart. Er war äußerst kompetent, geduldig und hat sich viel Zeit genommen, bis alles einwandfrei funktioniert hat.

    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...
