Does this sound familiar?
These challenges are part of my daily work
No suitable extension
There is no extension in the TER that meets your requirements – or the available ones are outdated.
Outdated extension
Your extension no longer works after the TYPO3 update. The original developer is unreachable.
No TYPO3 developer
TYPO3 developers are rare. Agencies often have no capacity or lack the required expertise.
Missing integration
You need to connect an external system (CRM, ERP, PIM) to TYPO3, but nobody knows how.
TYPO3 is my speciality
I am Vincent Kilchherr, and I have been developing TYPO3 extensions for over 11 years. From simple plugins to complex backend modules with Extbase/Fluid – I know the system inside out.
My focus is on clean code according to TYPO3 standards. No workarounds, no hacks – just extensions that still work after the next TYPO3 update.
