Self-management app
A tracker that never counts the days you missed
It counts what you accumulated, not your streak. Miss yesterday and today's one thing still adds up. Most of what I write here came out of building it.
Take a lookAbout
Only what I verified.
I build mobile apps and write down what actually happened. Not the tidy version - the wrong diagnosis first, then the measurement that corrected it. Most posts here started as a bug I could not explain, so they include the numbers I measured and the version of the tooling I measured them on.
What I write about
Topics Build log
Real problems from shipping a React Native app on Expo. Including the causes I got wrong first - those are usually the more useful half.
Ongoing 3D on device
three.js and react-three-fiber inside a phone app: asset budgets, what a GLB actually costs, and what the renderer quietly throws away.
Ongoing Automation
Handing repeated work to scripts. Measure, change one thing, measure again with the same instrument.
Ongoing Operations
Release, monitoring, analytics - everything that comes after the code works. Mostly: how I caught the failures that stayed silent.
