React Native Developer: cross‑platform mobile app development

Course overview

Description generated based on course syllabus and open data.

The curriculum focuses on practical cross‑platform development for both iOS and Android using React Native. Instructor: Viktor Yarmolytskyi, Senior React Native Developer at an S&P 500 company; 5 years in React Native; projects for the Ministry of Digital Transformation and products with multi‑million audiences.

React Native Developer: who it suits and who should reconsider

Suitable for a React Native / JavaScript developer

• Those coding in JavaScript who want one codebase for iOS and Android.
• Engineers with CSS background seeking modern styling and layout in React Native.
• ReactJS users planning to build mobile apps with familiar tooling.

Not a good fit

• Those targeting purely native Swift/Kotlin without JavaScript.
• Those seeking only theory without live coding and hands‑on practice.

Developer problems → approach and expected outcomes in React Native

• Problem: Fragmented styles and components. Approach: systematic Building Blocks, Styling, Layout. Outcome: consistent UI and scalability.
• Problem: Complex navigation flows. Approach: stack, tabs, modal navigation patterns. Outcome: predictable transitions and stability.
• Problem: Growing app state complexity. Approach: Redux Toolkit vs Context API, architectural patterns. Outcome: transparent data updates and fewer side effects.
• Problem: Integrating native APIs and services. Approach: native modules, Firebase, AsyncStorage. Outcome: robust integrations and offline support.
• Problem: Security and performance. Approach: safe storage practices, render optimization, profiling. Outcome: reduced data exposure and faster screens.

Comparison with alternatives in cross‑platform development for a React Native Developer

• React Native vs Flutter: RN uses JavaScript and the React ecosystem; Flutter uses Dart with its own UI renderer. Choice depends on team stack and UI requirements.
• React Native vs native (Swift/Kotlin): one shared codebase vs platform‑specific flexibility; RN suits shared logic with targeted native modules.
• React Native vs hybrid web wrappers: RN relies on native components rather than WebView‑based approaches.

Learning results for the React Native Developer role (competencies)

• Practicing component‑based UI and styling.
• Organizing navigation, state, and business logic.
• Integrating device native APIs and third‑party services.
• Setting up data security and performance optimization.
• Establishing CI/CD‑ready steps for deployment preparation.
