I will refactor legacy PHP code and upgrade to symfony or laravel
Andrei C.
About this gig
Legacy code is a ticking time bomb.
Is your business running on an old PHP 5.x application? Is your codebase a mess of "spaghetti code" that breaks every time you try to add a feature?
I am a Senior Software Architect with 17+ years of experience. I have been coding since the days of CodeIgniter and Vanilla PHP, and I have led the transition of enterprise systems to Modern Symfony and Laravel architectures.
I will professionally refactor your codebase:
- Upgrade PHP Versions: Move safely from PHP 5.6/7.x to PHP 8.2+.
- Framework Migration: Port legacy logic (CodeIgniter, Yii, CakePHP) into Symfony or Laravel.
- Performance Optimization: Refactor slow database queries (MySQL) and spaghetti logic for speed.
- Standardization: Apply PSR-12 standards, strict typing, and Dependency Injection to make your code maintainable again.
My Approach:
- Audit: I analyze the complexity and risk using tools like SonarQube.
- Test: I ensure current functionality is understood before touching a single line.
- Refactor: I rewrite the logic using modern patterns (SOLID, DRY).
- Verify: I deliver code that works exactly the same, but faster, safer, and cleaner.
Contact me with details about your current status.

FAQ
Will refactoring break my live website?
No. I never work directly on the live server. I require a staging environment (or I can help you set one up). I test the refactored code thoroughly on the staging site before we deploy it to production.
My code is very old (PHP 5.x / CodeIgniter 2). Can you handle it?
Yes. I started my career in 2007 working with Vanilla PHP and CodeIgniter. I understand legacy patterns perfectly and know exactly how to translate them into modern Symfony/Laravel standards.
Do you just rewrite the code, or do you change the logic?
My primary goal is "Refactoring," which means improving the code structure without changing the external behavior. However, if I find logic errors or security holes during the process, I will fix them.
Why is the Premium Package (Migration) so expensive?
Moving from a legacy framework (like CodeIgniter) to a modern one (like Laravel) is not copy-paste. It requires rewriting the entire architecture, routing, and database interaction layer. It is a complex engineering task, not a quick fix.
Do you offer a guarantee?
I guarantee that the code I deliver will follow PSR-12 standards and pass strict static analysis. I also provide a warranty period for any bugs directly related to my refactoring.
