Finn Glas

Finn is one of the Co-Founders of Contact Book. He owns the engineering side, the infrastructure that keeps the lights on, and most of the late-night fixes that ship before anyone notices. The architecture you read about under /security and /docs is largely his.

He works against a single principle: a tool ought to do what it claims, observably, on the day it claims. That shows up in the code as relentless invariants - access gates that never branch, audit logs that never silently skip, rate limits that apply identically to humans and agents. It also shows up in the deploy: blue / green, signed releases, no partial states reaching production.

He's been writing software professionally for a decade and contributes to a number of open-source projects in his spare time. Most of his architectural opinions trace back to the day he joined an on-call rotation for a system he hadn't designed - that's where the invariants come from.
