About

I'm really into mathematical optimization (that's why I'm here!), scientific computing, and the craft of writing high-performance code. Having earned a master's degree in mathematics, I transitioned from academia to the industry. I am now at Lufthansa Systems, using mathematical optimization for crew planning.
