About this gig

Is an old PHP or Laravel application blocking releases or consuming your team's time?


I diagnose and fix focused backend and full-stack issues in existing PHP codebases. With 16+ years of PHP experience and hands-on Laravel, Symfony, MySQL, JavaScript and PHPUnit work, I can help with reproducible bug diagnosis, broken features, database and integration issues, targeted legacy-code refactoring, regression tests where appropriate, and clear handover notes.


Please message me before ordering with the error, expected behavior, relevant logs and repository or access details. I will confirm the scope and recommend the right approach.


Available for confidential B2B and white-label agency work. I can sign an NDA and collaborate directly with your development team.
