NEED TO UPGRADE YOUR PHP VERSION OR FIX AN OUTDATED APPLICATION? Running an outdated PHP version? Concerned about security vulnerabilities, compatibility issues, or breaking your existing website during an upgrade? I can help. I'm a Senior Full-Stack Engineer with 12+ years of experience building, maintaining, troubleshooting, and modernizing production applications. I specialize in existing systems that already have users, databases, integrations, and business-critical workflows. I can step into unfamiliar codebases, understand how they work, identify problems, and implement improvements without unnecessarily rebuilding everything from scratch. 🔐 PHP VERSION UPGRADES & LEGACY APPLICATION MODERNIZATION Upgrading PHP isn't always as simple as changing a server setting. Older applications often contain deprecated functions, incompatible dependencies, outdated frameworks, or custom code that breaks when PHP is upgraded. I can help with: ✓ PHP version upgrades and compatibility fixes ✓ Legacy PHP application modernization ✓ Deprecated functions and breaking changes ✓ Laravel upgrades and maintenance ✓ PHP errors, warnings, and debugging ✓ MySQL and database compatibility ✓ Third-party API and integration fixes ✓ Dependency updates and security improvements ✓ Performance optimization and troubleshooting ✓ Testing and resolving issues after PHP upgrades My approach focuses on understanding the existing application, identifying compatibility risks, implementing the necessary changes, and validating that critical functionality continues working.

Much of my experience involves maintaining applications that businesses rely on daily. I'm comfortable taking ownership of a feature from start to finish, including requirements analysis, database and API design, frontend implementation, testing, debugging, and deployment. I also use modern development tools, including Codex and Claude Code, to improve development efficiency while personally reviewing, understanding, and testing the code I deliver.
