Senior Mobile Engineer delivering high-performance, scalable native-like apps.
TunisiaWhat I'm looking for
I am a Senior Mobile Engineer with 6 years building and leading mobile teams to deliver high-performance, scalable applications. I prioritize best practices, quality-driven development, and smooth native-like UI with careful attention to performance and testing.
I have led end-to-end mobile development: architecting apps, integrating native SDKs and Expo modules, managing App/Play Store deployments, and establishing CI/CD pipelines with Github Actions and CircleCI. I mentor teams, act as the primary mobile contact for cross-functional stakeholders, and implement unit, integration and E2E tests to ensure reliability.
My notable achievements include building MISPay from scratch as Senior Mobile Team Lead, improving app performance through profiling and monitoring, and shipping multiple consumer apps using React Native, Expo, Kotlin and related tooling. I am seeking opportunities where I can continue to lead mobile engineering, improve product quality, and mentor engineers.
