Mobile Architecture Review & Decision Framework
Review mobile architecture and make confident tech decisions
What You Can Do
This skill evaluates your mobile app's current architecture, identifies bottlenecks and risks, and guides you through structured decision-making for scalability, performance, and maintainability. You'll receive detailed analysis of your tech stack choices, platform-specific tradeoffs, and a clear action plan for architectural improvements or migrations.
Features
Evaluates native, cross-platform, and hybrid approaches for your specific use case. Compares iOS/Android/Flutter/React Native with cost-benefit tradeoffs.
Assesses your chosen frameworks, libraries, state management, backend APIs, and databases against performance, security, and long-term maintainability criteria.
Identifies bottlenecks in app startup time, memory usage, battery drain, and API latency. Recommends optimization priorities based on user impact.
Flags architectural risks (single points of failure, legacy code, deprecated dependencies) and quantifies technical debt impact on development velocity.
Structures complex decisions (monolith vs. microservices, native vs. cross-platform) with weighted tradeoff analysis tailored to your constraints.
Creates phased implementation plans for major architectural changes with clear milestones, risk mitigation, and rollback strategies.
Examines data flow, authentication patterns, encryption, and compliance requirements (GDPR, HIPAA) relevant to your mobile platform.
Aligns architectural recommendations with your team's skills and hiring roadmap. Identifies training needs or roles to hire for.
Example Output
Architecture Review Output Example:
Current State Assessment
- Platform: React Native (Expo) + Firebase
- Issue: Startup time 4.2s, database queries on main thread causing jank
- Risk: Firebase costs scaling with user base, no offline-first capability
Recommended Changes
- Migrate to React Native with Expo Modules for native performance (6 weeks)
- Implement Redux + Redux Persist for offline-first state (2 weeks)
- Add background sync service for resilient data updates (3 weeks)
Tradeoff Analysis
| Option | Time | Cost | Risk | Maintainability |
|---|---|---|---|---|
| Stay current | Low | High | Medium | Poor |
| Recommended path | Medium | Medium | Low | Excellent |
| Full native rebuild | High | High | Medium | Good |
