A senior Flutter developer focused on quality that lasts
I'm Mohammad Jrab, a Flutter developer with 4+ years of experience across product teams and freelance clients. I turn ideas into clean, maintainable code — and I'm at my best keeping apps fast, stable, and secure long after launch.
I specialize in maintaining, optimizing, and securing applications: profiling and eliminating jank and freezes, refactoring toward clean architecture, and hardening sensitive flows with JWT sessions, OTP verification, and screen protection. From the first commit to a published listing, I own the full iOS & Android release lifecycle on the App Store and Google Play.
