Senior Software Engineer building scalable, high-performance React Native apps with crash-free reliability.
PakistanWhat I'm looking for
I’m a Senior Software Engineer with 6+ years building scalable, high-performance React Native applications. I’ve delivered production-grade mobile apps with 2M+ user growth, 99%+ crash-free rates, and strong test coverage using TypeScript, Redux/Zustand, Jest, and CI/CD pipelines.
In my current role at Justlife, I developed and optimized a super app for 2M+ users, maintaining 70%+ unit test coverage across critical booking and payment flows. I improved stability and observability with Sentry and Firebase Crashlytics, implemented E2E automation with Maestro, and supported CI/CD through Bitrise to strengthen release reliability and regression prevention.
I also architect scalable, modular feature patterns (SOLID principles), lead performance profiling/refactoring for responsiveness, and drive data-informed improvements through A/B experimentation. I’ve built native modules in Swift and Java/Kotlin, modernized legacy code into modular offline-first systems with SQLite, and supported multilingual/RTL experiences across GCC/MENA audiences while owning App Store and Google Play submissions end-to-end.
