Hello! I'm Chaima Feninekh, a Senior React Native Engineer with 3+ years of experience building mobile apps at scale. I specialize in React Native with native iOS (Swift) and Android (Kotlin), and I love partnering with design to iterate on workflows and usability. I lead projects end-to-end, mentor junior engineers, and drive release trains with feature flags and experimentation. I’ve built scalable backends with Django and FastAPI on GCP, set up robust monitoring with Crashlytics and performance metrics, and automated CI/CD pipelines. I enjoy turning complex problems into maintainable, performant solutions and delivering reliable releases that users love.…Hello!
