Hello! 👋
3-time officially certified TYPO3 expert (Consultant, Developer & Integrator) for complex web projects, secure upgrades, and technical rescue missions.
Whether as lead developer for your agency's relaunch or as a consultant for sustainable system architecture: I take over where standard solutions end. I don't just blindly implement designs, but proactively advise on best practices, performance, and security – so that the TYPO3 foundation remains maintainable even in 5 years.
My Core Competencies
🚀 Relaunches & Architecture
- Development of tailor-made sitepackages and content elements (Fluid & TypoScript).
- Consulting on optimal architecture and tech stack selection.
- Focus on accessibility, modern frontend integration (HTML/CSS/JS), and performance.
⬆️ Upgrades & Migrations
- Secure major upgrades to current LTS versions (v12 / v13).
- Refactoring of legacy code and outdated extensions (e.g., PiBase to Extbase).
- Fixing deprecations for maximum system security.
🛟 Rescue Missions & Legacy Code
- Extremely fast onboarding into existing third-party systems.
- Stabilization and further development of stalled projects.
- Systematic troubleshooting and performance optimization.
⚙️ My Tech Stack
- CMS: TYPO3, TypoScript, TSconfig
- Backend: PHP 8.x, Extbase, Fluid, MySQL
- Frontend: HTML5, CSS3/SASS, JavaScript (Focus on integration, no UI/UX design)
- Tools: Composer, Git, DDEV, Docker, CI/CD
Do you have a personnel bottleneck in your agency or a TYPO3 project that needs to be elevated to a new technological level? Let's talk about your requirements without obligation!
