I build high-scale React Native apps with measurable performance, reliability, and security gains.
ItalyWhat I'm looking for
I've shipped React Native products for more than 100M combined users across Digikala, MyMCI, Agileful, and EasyMotionSkin.
At Digikala, I introduced module federation with Repack to cut build time 20%, shipped Turbo Modules that improved performance 25%, and profiled memory leaks and unnecessary re-renders to reduce CPU usage 30%.
While leading MyMCI's five-engineer mobile team, I delivered three major releases with zero critical rollbacks, reduced release time 40% through GitHub Actions CI/CD, and strengthened app security with SSL pinning, MITM protection, root detection, and JailMonkey.
I'm also building Chrona, a Mac and iPhone time-tracking app on TestFlight with on-device inference and cross-device activity sync, while pursuing an MSc focused on on-device ML and applied LLM systems.
