Sascha was my co-worker at grandcentrix where we were facing challenging technical problems every day. He proved his skills as an excellent backend developer as well as a very capable solution architect where it was required for him to see the big picture and to think outside the box. By his very nature, Sascha always strives to share knowledge and establish a culture of team thinking and respect. He is able to very quickly take a lead role in a team he's part of and and always comes up with ways to improve processes, tools as well as team spirit in general. It was a pleasure working with him and I sincerely hope we'll meet each other in a professional context in the future again.

Sascha has been one of our most influential developers. He dived into the Elixir and Erlang ecosystem, taking ownership of his projects right away. Sharing his experience comes naturally to him either as a mentor or a speaker. He left his mark on our company culture has been the organizer and initiator of several events as well as emphasizing the importance of compassionate coding.
