Project details

You'll get a modern, secure PHP codebase without breaking what already works. Running PHP 5.6 through 8.1 means zero security patches, since all of these versions are officially end-of-life. I migrate legacy applications to supported PHP versions (8.3/8.4), fixing deprecated functions and compatibility issues along the way.

With over 10 years maintaining a production PHP SaaS platform through multiple major version migrations, I know how to upgrade code without breaking live functionality. Every project starts with a full backup, so your site is never at risk during the process.

You'll get a working, tested application on a currently supported PHP version, plus a clear list of what changed.

PHP Web Developer | Server Admin (cPanel/WHM) | Website Migration
Izmir, Turkey - 6:32 am local time
I'm a full-stack PHP developer and server administrator with over 10 years of experience building and running a live SaaS platform used daily by real, paying clients in the Turkish travel industry. I handle the entire technology stack, from writing the code to managing the servers it runs on.

- Web Development: Custom PHP web applications, admin panels, WordPress sites, ecommerce integrations, and full-stack feature development

- Server & Infrastructure: cPanel/WHM setup and management, LiteSpeed configuration, Cloudflare setup, dedicated server deployment, mail server configuration (DKIM/SPF), and performance optimization for slow-loading sites

- Migration & Maintenance: Legacy PHP version upgrades, malware removal and security hardening, ongoing bug fixes and new feature rollouts on production systems

- Payment & Automation: Payment gateway integrations for ecommerce and booking systems, plus scripting and automation for repetitive tasks and data collection

I communicate primarily in written English and use professional translation tools to ensure clarity and accuracy. I'm happy to work via chat, email, or async communication for smooth collaboration across time zones.
