I will maintain, fix, or modernize your legacy PHP codeigniter application
Hassine K
About this gig
Do you run a business application built on CodeIgniter 3 or legacy PHP that needs maintenance, bug fixes, or compatibility updates?
You do not always need an expensive rewrite. A well-maintained legacy application can remain stable, secure, and fast with targeted refactoring.
I am a Senior Backend Engineer with a BSc in Computer Engineering. I specialize in maintaining, debugging, and modernizing production PHP codebases that others avoid.
Services offered:
PHP version upgrades (resolving fatal errors & deprecations for PHP 8.1 - 8.3)
CodeIgniter 3 maintenance, bug fixes & feature development
Database query optimization & resolving legacy SQL issues
Integrating modern REST APIs and automated webhooks into older apps
Code cleanup: organizing legacy controllers and business logic
Safe migration roadmaps toward modern frameworks (Laravel)
How I protect your live system:
- Strict local/staging testing before touching production
- Full database and file backups before any change
- Clean Git commit history documenting every line
Message me with your PHP version and requirements before ordering.

I focus on clean architecture, security, and maintainable code.

FAQ
Can you make CodeIgniter 3 run on PHP 8.1 or 8.4?
Yes. I patch framework core deprecations, update libraries, and refactor custom application code that breaks on modern PHP versions.
Can you add a modern REST API to an old CodeIgniter app?
Yes. I can create RESTful controllers returning clean JSON payloads, allowing you to connect mobile apps, frontends, or third-party webhooks.
Do you need direct access to my live production server?
No. I strongly prefer working on a Git repository clone or staging environment to ensure zero disruption to your active users.
Can you help migrate our system to Laravel later?
Yes. I can audit your database schema and business logic, prepare clean data models, and create a phased migration roadmap to Laravel.
