Freelancer profile translated to English.

Description

Senior PHP Developer with over 25 years of experience in web development. My focus has been on the Symfony framework since Symfony 4 — with common design patterns, clean code, and test-driven development (TDD). For over 15 years, I have also been developing WordPress themes and plugins, consistently adhering to WordPress standards and security criteria.

I take on clearly defined projects that can be implemented predictably: new features, REST APIs, WordPress plugins and themes, bug fixing, performance optimization, and smaller relaunches. My focus is on the backend — I cleanly implement existing designs or collaborate with designers for them.

What you can rely on: tested, maintainable code (PHPUnit/TDD, static analysis), adherence to common PHP and WordPress standards, and a clear focus on stability, security, and performance. I work pragmatically and functionally, without unnecessary overhead.

Communication with me is direct and honest: I clearly state what I consider sensible and estimate effort realistically instead of making pretty promises.

Since the beginning of 2026, I have been working as a full-time freelancer and am therefore fully available — for remote projects as well as on-site if required. Feel free to contact me with your project, and I will get back to you promptly with an honest assessment.
