Freelance and spare-time programmer, mainly embedded stuff. Old-timer, started in 1976 (Tandy TRS-80).
Assembler, C/C++, a little Java, PHP, and various others on the side. C programming, static code checking and build concepts are specialties, as are the tools involved (PC Lint, QA-C, PolySpace, GNU make, ...)
Mostly using Win10 and CLI-Linux/bash these days. Geek interests: Operating systems, compiler construction and code generation, networking, security and privacy.
