    Experience

    • 1+ years of experience in React, ideally React Native
    • Work experience or hobby experience with React Hooks
    • Innately curious with a desire to learn and teach, and an excellent command of engineering fundamentals
    • Innately curious to build apps used by users that love your app

    Our Stack at Fintros
