How I Can Support You

From Concept to Reliable System – Web Solutions with Structure and Vision

Professional PHP development and IT consulting for businesses of all sizes

🔧 Legacy Code Modernization

Especially valuable in complex system landscapes: I modernize outdated PHP applications securely, systematically, and without downtime – with a focus on long-term stability.

What I modernize:

  • • PHP 5.x → PHP 8.3 migration
  • • Updating outdated frameworks
  • • Fixing security vulnerabilities
  • • Performance improvements and refactoring

Your benefits:

  • • Significantly faster load times
  • • Up-to-date security standards
  • • Maintainable, documented source code
  • • Future-proof architecture
  • • Seamless migration during live operation

Real-world example: As part of a project for a leading energy solutions provider, I led the migration of a large PHP codebase from version 7 to 8. This included Composer updates, replacing deprecated functions, and optimizing existing structures for better maintainability and performance.
