Introduction:

Hi, I'm Piyush Nanwani, a Mobile App Developer with over 4+ years of experience. Having been through numerous job interviews and conducted over 50 interviews myself, I've compiled this React Native roadmap based on an analysis of 100+ job descriptions from platforms like LinkedIn and Naukri.

This roadmap is designed to guide developers at various experience levels, covering essential, intermediate, and advanced skills in React Native development. Whether you're starting your journey or looking to enhance your expertise, I trust you'll find this roadmap insightful and beneficial.

🌟 Bonus: This guide isn't just for developers! Recruiters and hiring managers seeking React Native talent will also find valuable insights. 🤝
