summary

Senior Laravel developer with over 15 years of PHP experience. I modernize legacy systems — incrementally, without risky full rewrites.

Most legacy projects don't need to be rebuilt from scratch. They need someone who can step-by-step modernize them, reduce technical debt, and deliver value along the way. That's exactly what I do.

Currently working on migrating RPG/AS400 systems to Laravel. Previously transformed Drupal applications into modern, maintainable solutions. Different starting points, same approach: practical modernization that works with the framework.
