How to become a Mobile Engineer (cross-platform)
Build apps people carry, one codebase shipping to both stores: Flutter or React Native, real state management, and something published.
Best for
Students who want their work in someone's hand and would rather cover both platforms than specialise in one. Also the pragmatic choice for a solo developer or a small startup.
Maybe not for you if
If you want the deepest platform expertise, take the Android Engineer or iOS Engineer roadmap instead - native roles typically ask for the platform SDK in far more detail than a cross-platform framework teaches. And if you want the widest set of campus openings, web and backend paths typically have more.
The 4 phases
What each phase gets you to. The steps, resources and checkpoint inside each one open with a free account.
Phase 1 - Language and programming fundamentals
4-5 weeksGoal: Write confident code in your framework's language, and run your own builds on real hardware.
3 steps · ends in a scored checkpoint (60% to clear) · assumes basic programming
Phase 2 - UI, state and lifecycle
6-8 weeksGoal: Build a multi-screen app with real navigation, state that survives rotation, backgrounding and process death, and screens that still work with the network off.
4 steps · ends in a build deliverable
Phase 3 - Ship something real
4-6 weeksGoal: Get a signed build into other people's hands, ideally through a live store listing, and keep it healthy after launch.

Phase 4 - Clear the process
3-5 weeksGoal: Pass the standard coding and aptitude rounds, then hold your own in the mobile-specific technical round.

What hiring actually looks like here
Mobile hiring is commonly portfolio-driven: a published app usually carries more weight than a listed skill. In Indian listings, Flutter shows up more often for standalone mobile roles, while React Native appears where the company already runs a React web team. Cross-platform experience is often valued most at startups and product companies shipping to both stores, while larger platform teams frequently hire native. Campus processes still typically run the standard DSA and aptitude rounds.
