Project details
I’ll diagnose and fix bug in your PHP application with a root-cause approach so you get reliable, long-term fixes — not temporary patches. I combine careful debugging, code cleanup, and targeted testing to restore functionality, improve performance, and reduce future errors.
What I’ll Do (Scope)
Rapidly reproduce and diagnose reported issues (errors, crashes, unexpected behavior).
Fix logic, syntax, session/authentication, form handling, and DB query problems.
Resolve PHP warnings/notices and deprecated function usage.
Improve fragile code paths and add basic input validation/sanitization where needed.
Run unit/manual tests for fixed areas and verify in your staging/production environment (as allowed).
Provide a short changelog & recommendations for ongoing maintenance.

Remove malware and clean https://heatnotburn.co.uk
This is the second time that I have used Nawalage for work on my Wordpress/Woocommerce website.
I find Nawalage to be excellent, he is very prompt, understands the issues and works quickly to get them resolved. I would recommend Nawalage as I think he is a very good freelancer. He removed a load of malware from my website in a timely manner.
