Kind words

What clients say.

“Hannes moved our app from Vercel to its own secure AWS environment. With a staging system and automated tests, we are now much better prepared to handle sensitive health care directive data.”
Tien Hào VuHead of Service & Management Consulting, blu Systems GmbH
“Hannes built our integration platform on his own and still looks after it today. It processes hundreds of integrations every week on real customer data – reliably, and without us having to worry about it.”
