Rockstar🎓
Top SchoolReini Urban is a pragmatic senior software engineer with 30 years of cross-domain experience from embedded bare-metal firmware to compiler and VM internals, now focusing on AI and embedded systems in Dresden. A true generalist, he has shipped low-level C/C++ firmware for AVR/STM32 and contributed lasting open-source work—maintainer and contributor to projects like LibreDWG, Parrot VM and smhasher—bridging file formats, hashing, and interpreter/compiler tooling. He pairs hands-on systems engineering (tests, simulators, formal verification) with decades of CAD, measurement and motorsport tooling experience, having supported F1 teams and developed specialized cross-compilers and devices. Notably, he authors and maintains numerous foundational libraries (safeclib, libredwg, cperl and Perl5 compiler modules) showing a preference for enduring, portable C software. Reini brings a rare combination of deep low-level expertise and practical product focus, able to move between hardware, firmware, and complex open-source ecosystems.
