My thoughts on building systems, thinking with data, and learning through real projects.
Everything
Every post in one place, newest first. Projects are systems I've built end-to-end. Opinion pieces are shorter takes on what I've learned along the way.
Part 2 of a series on BILBO, a home-built baby monitor. Six opinions about privacy architecture and shipping ML under real constraints, the bugs that cost me a morning each, and the new failure modes coding agents introduce that nobody is talking about yet.
