My main goal has been to avoid undefined behavior and security vulnerabilities. People would deem this impossible with C for practical purposes, but I think it's just a matter of responsibility, discipline and devotion. I've done extensive error checking, taken all compiler warnings seriously and employed security recommendations like the usage of goto chains. There's of course still a lot of room for improvement and certainly numerous bugs, but one small step at a time...
I'm moving from full-stack web development to system, application, low-level or embedded programming of some mission criticality. If you have a vacancy and see potential for a good cooperation, please drop me a line, my e-mail address is on my Github. I'm based in Berlin, Germany and willing to relocate across continents.
If any discussion arises I will be available in the European afternoon to address your questions.
