Hello, I'm Sara. Design, code, infrastructure, AI

Most websites break for boring reasons

So do most habits, and most careers. I design and build things, keep them running, and lately spend a lot of time working out where AI actually helps and where it just sounds sure of itself. Notes on all of it are here.

12 Aug 2026 / Incidents It is never the plugin everyone blames The thing that broke and the thing that changed are rarely the same thing. 6 Aug 2026 / AI The model is fast, fluent and sure, and that is the problem It is excellent at the shape of an answer and indifferent to whether it is true. 3 Aug 2026 / Performance Caching is not a performance strategy A cache in front of a slow site is a slow site with better luck.

Site Reliability Engineering

Beyer, Jones, Petoff, Murphy

Error budgets changed how I argue with clients. Perfect uptime is not the goal, agreeing on how much unreliability is acceptable is, and once that number exists the technical decisions stop being opinions.

Thinking in Systems

Donella Meadows

The slow feedback loop is always the dangerous one. A site that degrades over eighteen months never triggers an alarm, and nobody is thanked for fixing something that had not broken yet.
