SKILL.md7.0 KB

Overview

This skill is my cross-platform mobile developer profile focused on building performant native experiences with React Native (0.72+) and Flutter (3.16+). I deliver optimized apps that prioritize platform-specific UX, battery efficiency, and high code reuse while meeting strict performance and size targets. The skill encapsulates architecture analysis, native module integration, offline sync, and app store readiness.

How this skill works

I start by requesting platform context to learn target OS versions, existing native modules, and performance baselines. I audit native code and benchmarks, then implement shared business logic with platform abstractions while applying native UI patterns. Finally, I profile startup, memory, and battery metrics, tune builds, and prepare automated deployment and crash monitoring.

When to use it

Building a cross-platform app that must feel native on iOS and Android
Migrating or integrating native modules (camera, Bluetooth, biometrics) into shared code
Optimizing an app for startup time, memory, battery, or bundle size
Implementing robust offline-first sync, delta sync, and retry strategies
Preparing builds for App Store/Play Store with signing and distribution pipelines

Best practices

Target >80% cross-platform code reuse while keeping platform-specific UI idiomatic
Design offline-first data with local DB, queue management, and conflict resolution
Profile cold start, memory, and battery on real devices; optimize assets and bundles
Use native gesture handling, adaptive layouts, and accessibility from the start
Automate builds, signing, and beta distribution (fastlane, CI) and monitor crashes/ANRs continuously

Example use cases

Ship a React Native app with 85% shared logic, Face ID on iOS, and Material components on Android
Add encrypted local storage, delta sync, and exponential backoff to a spotty-network app
Integrate camera, GPS, and Bluetooth with platform-specific modules and tests
Tune app to meet cold start <2s, initial download <50MB, and memory baseline <150MB
Set up CI/CD for automated builds, beta releases, crash reporting, and store submission

FAQ

Cold start under 2s, baseline memory <150MB, battery <5%/hr, 60 FPS scrolling, and app size under 50MB initial download.

How do you approach offline synchronization?

I implement a local DB, action queue with retries and exponential backoff, delta sync, conflict resolution rules, compression, and cache invalidation policies.
