I'm a Technical Architect at GitHub.

I've invented a new, cloud-native, easy-to-use version control system, called Grace, and you should totally check it out. ❤️

I've been a programmer since age 11, starting with the Apple ][+, AppleSoft BASIC, and 6502 Assembler. Since then, I've learned and mostly forgotten tons of other languages, operating systems, and server and client software, during a long career in which I've been a programmer, network administrator, DBA, consultant, architect, Program Manager, and Product Manager.

My most current resume, with a long list of stuff I know (and stuff I used to know) and stuff I've done is here.

After 18 years of object-oriented programming (C++, VB.NET, and C#), around 2016 I started to explore the mathematical and functional end of programming. I learned some Category Theory and even some Category Theory II (for free on YouTube from a great teacher, the world is amazing) and what a monad is, and now I write code mostly in F#. F# is just fun. It has a beautiful, minimal syntax, a full library of functional constructs plus access to the entire .NET ecosystem, it's strongly-typed, and it's very fast.

The journey from object-oriented(-ish) thinking to functional(-ish) thinking can take time - think months, not weeks - but I'd like to report from the other side of that journey: it's worth it, both for quality and for developer ergomonics. Loved it, would recommend.

I wish I could be good at All The Things, but there's just too many of them, so I specialize in cloud architecture using Microsoft Azure, and programming in .NET. I 💛 PaaS, virtual actors, CQRS and Event Sourcing.

Hi from a little bit east of Seattle. ☁️

Don't forget to check out Grace. 😉

Lucky to have a great girlfriend, a great family, and more friends than I know what to do with.
