Hi, I'm Sef

I'm an engineer and dad and tinkerer. I'm an early retiree from a thirty-year career in Tech.

I write an old-style blog. You can read posts by date or browse one of the categories below. I hope you check it out.

My career has been working for tech companies like Google, VMware, Ning, and Akamai, as well as some startups. My resume has the whole story. The most fun was building an online education site for Stanford during the MOOC boom of 2012.

Lately I've been helping (in small ways) to protect Democracy here in America. I worked with another Stanford team to relaunch DataTalk, a tool to help investigative journalists use campaign finance data (post). And I wrote Leafletter, a little app for community organizing (post).


I support the work being done by my local Indivisible chapter and the national No Kings movement.

I also play board/video games and am learning bridge. I keep coming back to tech projects, ever since I spent a whole summer hand-coding a robots game way back when.

If any of this interests you too, reach me via email (preferred) or @sefk on Mastodon.
