   Phase 1: Learning Language and Platform Fundamentals

   2–3 months

   Working through structured lessons in Swift, Kotlin, or a cross-platform framework like Flutter or React Native, writing small exercises daily. By the end, the person can build simple screens, handle user input, and run apps on a simulator or device.

   You're done when you can show

   A GitHub repo of completed tutorial exercises and small practice apps.

   Phase 2: Building Complete Solo Apps

   3–4 months

   Designing and coding two or three full apps from scratch that use networking, local storage, navigation, and third-party APIs, debugging their own problems without a tutorial to follow. They produce polished, working apps that show real architectural decisions.

   You're done when you can show

   A GitHub repo with a README and screenshots for a fully functional original app.

   Phase 3: Shipping to App Stores

   1–2 months

   Preparing an app for release by handling signing, store listings, privacy policies, crash reporting, and review feedback, then publishing it and pushing updates based on real user reports. This proves they can take software all the way to production.

   You're done when you can show

   A live App Store or Google Play listing link for their published app.

   Phase 4: Applying and Interviewing for Roles

   2–4 months

   Packaging the portfolio, contributing to open-source or freelance gigs for references, practicing coding and system design interviews, and applying to mobile developer positions. The phase ends with a signed offer or paid contract.

   You're done when you can show

   A signed job offer letter or freelance contract for mobile development work.

   Phase 5: Delivering Features on Teams

   1–2 years

   Working inside a production codebase, shipping features through code review, CI pipelines, testing, and release cycles while collaborating with designers and backend engineers. They prove they can own features end to end in a professional team environment.

   You're done when you can show

   Release notes or a merged pull request credited to them for a shipped production feature.
