Ramiz R.

Sr. Mobile Engineer & Tech Lead | Android, iOS, Flutter, React Native

I'm a mobile technical lead with 12+ years building, stabilizing, and shipping production apps across Android, iOS, Flutter, and React Native. Teams bring me in when an app is unstable or a release is stuck — I inherit messy codebases, drive down crash rates, unblock release pipelines, and ship SDKs other developers build on. Recent work: • Yahoo Fantasy Sports — redesigned core user-facing screens and refactored from MVP to MVVM, cutting the crash rate to target. • Portal (Web3 wallet) — led the Android and React Native SDKs that other teams integrate. • Unified Remote — Android app with 10M+ installs worldwide. • Plume — B2B Android app with multiple product flavors used across 10+ businesses. Native depth, cross-platform range: • Android — Kotlin, Java, Jetpack Compose, Coroutines, Clean Architecture (Google Certified Associate Android Developer). • iOS — Swift, shipped multiple apps end-to-end from Figma to App Store and post-release maintenance. • Flutter — Riverpod, GetX, GoRouter, Dio. • React Native — app development and SDK maintenance. • Firebase — Auth, Firestore, Remote Config, Cloud Messaging, Crashlytics, and on-device ML. I write clean, maintainable code, take full ownership of delivery, and build stable, performance-focused apps that hold up in production. If you need someone who can both lead the architecture and ship the hard parts, let's talk.
