Uses

36GB. The RAM matters more than the cores when you keep four Chrome profiles and a Docker stack open.

Single display, not two. Fewer places for a Slack notification to hide.

Low profile, quiet enough for a call I forgot to mute.

The on-device test unit. A simulator will lie to you about haptics, camera, and real network conditions.

Kept next to the iPhone for the same reason — Android is where React Native's cross-platform promise actually gets tested.

Vitesse Light, JetBrains Mono at 14px, line height 1.7. Format on save, no exceptions.

Replaced ESLint and Prettier on new projects. The speed difference is not subtle.

Starship prompt, trimmed to branch and node version only.

Open for the simulators and native build tooling, not for writing code in either.

The actual dev loop for the React Native work — prebuild, dev client, and OTA updates without a store release.

Performance and Coverage panels. Almost everything I've written about performance started in one of the two.

Throttled mobile, Cape Town test location. Lab numbers from a fast desktop are a story, not data.

Field data settles arguments that lab data starts.

Replaced Flipper in the stack. Component tree, network, and the profiler in one place, without a separate app running.

Next.js, self-hosted fonts, deployed on Vercel. No client-side framework on article pages.

With visual regression. The subject of one of the more useful things I've written.

Cloud builds for both platforms from one config, then straight to store submission without touching Xcode or Android Studio's own release flow.

Where a build actually lands in front of a client before it reaches the store.
