I've been writing software professionally for more than 25 years. I'm a systems programmer with strong interests in network and host management, middleware and security. Professionally, I've been writing embedded software for automotive applications for roughly the last 10 years.
Prior to my automotive work, I was a UNIX network management software developer and system administrator for many years. I continue to develop UNIX software (primarily in C++), since it's my primary hobby. I've been doing what we now call DevOps since long before that name appeared. I also dabble in embedded work as a hobby, from small 8-bit microcontrollers up to devices like the Raspberry Pi.
