We, Oliver Kattwinkel and Christian Klassen, are the founders of Kleenecode and started working together in 2012. Both of us share the passion of building progressive software systems with high quality and minimal yet functional design. After having gathered important experiences in different industry sectors, we decided to join our skills and start our own company in 2019.
Oliver Kattwinkel started his professional career as a scientific research assistant at the Bonn-Rhein-Sieg University of Applied Sciences (HBRS) and worked in cooperation with the Fraunhofer Institute. His key topics concerned the technical principles of Blockchain systems as well as the practical application of this emerging technology. His major projects include a protocol specification for asynchronous cryptocurrency payment data exchange (Bitcoin) as well as the development of decentralized applications and smart contracts, such as a community based sharing network on the basis of the Ethereum Blockchain as an open, transparent and decentralized data layer.

He worked as a technical architect for the leading provider of intelligent process automation in Germany and supported the implementation of larger automation projects in Europe.
