React Native Development

React Native Bridge Modernization

You inherit a brownfield repo with staged flags. Each week toggles another surface while keeping ship lanes open. The final artifact is a migration comic strip—panels that executives can follow without reading ObjC.

Cohort questions

Expo?

Comparisons appear, but exercises assume bare workflow parity for native module weeks.

Windows dev machines?

Android path is fully supported; iOS modules require macOS hardware or paired teammate.

Limitation?

We do not cover brownfield web views inside RN beyond a single escape hatch example.

Notes from recent seats

“Hermes week finally made the memory deltas legible to our PM. Still heavy prep, worth the nights.”

— Sam , Platform engineer

“Rollback drills mirrored our incident ritual; appreciated the blunt blast-radius worksheet.”
