TipTopCarbon
Germany · 2026
A configurator that lets customers put together their own carbon part, connected to the processes behind it.
Many businesses adapt their processes to their software because there's no other way. I turn that around. Whether it's a customer portal, an internal dashboard, a booking system, an integration between two systems or a mobile app: I build software that mirrors your processes, saves time every day and feels natural to the people who use it.
As a senior developer and former lead developer at an international company, I design the architecture so it grows with you. I also run a software development company in the USA, kristofhulmann.com, and my own products such as the Android app Kristoftalks show that I don't just build software, I run it too.
