I am a senior full-stack developer specialising in TYPO3, Magento 2 and React / Next.js. I build custom business applications, e-commerce platforms and modern frontends, carry out major CMS upgrades, and provide reliable long-term support in production.
The technologies I use every day to deliver fast, maintainable web platforms.
My professional background and key responsibilities.
Public websites I have worked on as part of development teams during my employment.
A large-scale TYPO3 platform for a nationwide operator of senior residences. I developed several custom extensions, including backend modules and frontend features built with Extbase and Fluid, and was involved in every phase from requirements analysis to deployment, testing and maintenance.
A highly customised Magento shop for made-to-measure products. I developed product configurators with dimension calculations and real-time 3D visualisation.
A Magento B2B shop for emergency and rescue equipment. I worked on product configurators, form validation, checkout customisations and tailored ordering processes.
Reusable JavaScript web components that allow Wera products to be embedded on third-party websites without CSS or JavaScript conflicts. They work on desktop, tablet and mobile devices and support 3D product views.
Development of custom TYPO3 extensions, including backend modules, frontend features and UI/UX improvements, as well as responsive layouts and ongoing maintenance.
Responsive frontend applications built from design mockups, with reusable React components and API integrations, through to testing and production deployment.
Upgrades of numerous TYPO3 projects from versions 8, 9 and 10 to TYPO3 13: core updates, migration of custom and third-party extensions, refactoring of deprecated code, database migrations, regression testing and bug fixing, ensuring that all existing functionality continued to work after the migration.
