Profile
Alexej Liebenthal
Lead Software Engineer
Lead Software Engineer with over ten years of experience. Started in the German Air Force developing geographic information systems at Airbus. Today I build cloud platforms for the insurance industry, responsible for architecture, team, and budget, and have shipped multiple of them to production in regulated environments. I stay hands-on and write code when time allows, with a focus on clean architecture, developer experience, and helping others grow.
