Tim Hehmann is a web developer based in Berlin with 10 years of hands-on experience building full-stack applications and automating testing pipelines. He has shipped cross-platform mobile and web features single-handedly using Angular, Cordova, PHP/MySQL and modern front-end stacks, and improved developer feedback loops as a Python engineer at Siemens by converting manual hardware tests into automated suites for ETCS diagnostics. Trained at the Hasso-Plattner-Institute in IT-Systems Engineering (BSc and MSc), he blends disciplined engineering rigor with a persistent, curiosity-driven approach honed on Project Euler challenges. Colleagues describe him as tenacious and resourceful—someone who stays up late to learn the trick that breaks a problem open. Outside work he channels focus into bouldering, snooker, guitar and video editing, which he credits for creative problem-solving and attention to detail.
