Custom Software Development

Whether Laravel, Symfony, or legacy code—I develop and optimize customized solutions. From modernizing existing systems to implementing new features, I ensure that your application remains maintainable, future-proof, and high-performing.

Data Processing

Data is the fuel of modern applications. I import, export, transform, and structure information so that it is reliably available and creates real added value for your business.

Analysis and Testing

More efficient processes, more stable applications: Using targeted analyses, code reviews, and tests, I identify potential for optimization and increase the performance and reliability of your software.

Online tool for radio program planning

An existing application for managing large music databases was prone to errors and became increasingly slow as the volume of data grew. It also lacked modern features for efficient radio program planning. After a thorough analysis of the proprietary framework, I fixed critical bugs and significantly improved the performance of database accesses in some cases. Over several years, I adapted the application to new PHP versions up to 8.4, which significantly improved stability, speed, and security. In addition, I switched to Composer for modern dependency management.

Tasks
  • Migration from PHP 5 to current PHP versions (up to 8.4)
  • Performance optimization of complex database queries
  • Bug fixes and optimization of the proprietary framework
  • Introduction of Composer for dependency management
