Mobile App Engineering

For mobile engineers: build native + cross-platform apps and ship them past store review. — built in-house by Skill Me.

The mobile stack the catalog was missing. Reach for it when you own an iOS, Android, Flutter, or React Native app end to end: build UIs with correct state flow and no recomposition jank, add local-first offline sync with real conflict resolution, wire APNs/FCM push from token to tap, profile dropped frames and memory leaks against a frame budget, and get through App Store Connect and Play Console submission without the usual signing and privacy-form rejections.

Skills in this pack

• SwiftUI Expert — Builds clean, performant, accessible SwiftUI views with correct state ownership, scoped invalidation, and smooth list scrolling, and reviews existing SwiftUI code against a concrete frame-time and re-render budget.
• React Native Pro — Builds and ships production React Native apps - architecture, navigation, list and startup performance against explicit budgets, native modules, and EAS release flow.
• Jetpack Compose Builder — Builds Android Jetpack Compose UI with hoisted state, unidirectional data flow, and recomposition-safe patterns backed by measured stability rules.
• Flutter Widget Architect — Architects Flutter widget trees and Riverpod or Bloc state so rebuilds are scoped, build() stays pure, and const widgets skip recomposition.
• Mobile Offline Sync — Builds local-first mobile storage with an optimistic local store, durable mutation outbox, per-entity conflict-resolution rules, incremental pull, and idempotent background retry.
• Push Notification Wirer — Wires native mobile push end to end on APNs and FCM - device-token lifecycle, permission priming and prompt timing, alert and silent payloads, the server send path, and tap routing in all app states.
• Mobile Perf Profiler — Diagnoses and fixes mobile jank, dropped frames, slow startup, and growing memory by capturing a trace or heap snapshot on a real device, isolating the single worst cost, fixing it, and re-measuring against the 16ms frame and cold-start budgets.
• App Store Release Prep — Produce a reproducible signing, versioning, and store-declaration pipeline so an iOS or Android build passes App Store Connect / Play Console submission.
