Expert PHP: Refactoring & Optimization

$55/hr Starting at $500

Does your PHP application suffer from slow load times, spaghetti code, or outdated architecture?

As a Senior PHP Developer with 10+ years of experience, I specialize in handling heavy-lifting backend tasks that require a deep understanding of PHP internals, server environment, and database interactions. I help businesses stabilize and optimize their existing codebases.

This service is focused on "under the hood" improvements rather than building new features from scratch.

Core Services:

  • Legacy Code Modernization: Safely upgrading old PHP applications (e.g., PHP 5.x/7.x to 8.x), refactoring monolithic procedural code into modern OOP standards, and introducing composer-based workflows.

  • Performance Tuning: Identifying bottlenecks using profiling tools (Xdebug, Blackfire). Optimizing slow MySQL queries, implementing proper indexing strategies, and setting up caching layers (Memcached/Redis) to drastically reduce server response times.

  • Complex Backend Logic: Implementing intricate business rules, background processing, data migration scripts, and heavy calculation engines that require efficient resource management.

  • Security Audits & Hardening: Reviewing code for common vulnerabilities (SQL Injection, XSS, CSRF) and securing API endpoints.

My Approach:I approach legacy code with caution. I ensure that refactoring is done incrementally, often introducing tests first to guarantee that existing functionality remains intact during modernization.

When you need an expert to dive deep into a complex PHP problem and emerge with a clean, optimized solution, I am here to help.
