About this gig

Console flooding? Script crashing on load? Ill trace, fix, and stabilize your JavaScript fast.


Specializing in vanilla JS, ES6+, and cross-framework debugging, I resolve syntax, runtime, async, and DOM errors without breaking your existing code.


WHAT I FIX:

Uncaught TypeError, ReferenceError, SyntaxError

Async/await & Promise rejection crashes

Event listener & DOM manipulation bugs

Third-party script conflicts & version mismatches

Memory leak triggers & infinite loops


PROCESS:

1. Share console logs + reproduction steps

2. I diagnose root cause using DevTools

3. Deliver clean fix + clear explanation

4. Test approve done


️ SCOPE: Client-side JS only. No Node.js backend, server configs, or full rewrites. 1 error = 1 distinct issue.


 WHY ME:

Fast response (<10 mins) & 6h delivery

Clean, documented fixes

Free revision if scope matches


Complex issue? Message first for FREE diagnosis. Order now and stop wasting hours debugging.
