Engineering deep dives, building in public, Bitcoin sovereignty, and first-principles thinking.
Six dedicated servers in a German data centre, and a multi-tenant Kubernetes platform on top of them. Most of what I run my life on now lives there. This is an honest account of why I built it, what it actually costs, and the situations in which you absolutely should not do the same.
I have two children. They will grow up in a world where Bitcoin is part of how families save, spend, and pass on wealth. Software good enough for non-technical families to do this safely does not yet exist. So I am building it — in public, decision by decision, with the next generation as the only deadline that matters.
Python on Knative was costing me 5–7 seconds every cold start. On a small Kubernetes cluster, that latency was the difference between a usable AI agent and a broken one. So I rewrote four services in Go on three weekends. Here are the measured numbers, the unexpected wins, the unexpected pains, and when you absolutely should not do the same.
Everything you need to know about reducing your AWS bill by 20-40% — from quick wins to architectural changes.
Datadog was costing us $40K/month at 1 TB/day. We were growing to 6 TB. Instead of scaling the bill, we built our own platform that ran 8× cheaper at production scale.
