Background

About

I came to software from operations, most recently running a 260-person logistics team in Zambia. That background is why I build the way I do: I ask what the software has to do on a bad day, ship the smallest thing that does it, and make sure it keeps working. Since 2022 I have built products for clients and communities, and during reserve service I built tools my unit still uses.
