About Me

Jeff using a computer in the 90s I’m a Quality Assurance Engineer and Team Lead in the automotive software industry here in Tokyo. In a past life, I was an iOS and macOS developer and teacher in San Francisco. In an earlier life, I earned my Bachelor of Science in Industrial Design at San Francisco State University.

In my spare time I still enjoy working on Apps and I am very interested in Retro Computing, specifically with old Macs, Mac OS X, and NeXTSTEP. I try to share everything as much as possible on this site and on social media:
