Team Lead / Senior React Native and React JS Engineer

I build and ship cross-platform React Native applications and own the complete release lifecycle, including CI/CD setup, code signing, staged rollouts, and publication to the Apple App Store and Google Play Store. I integrate third-party SDKs and REST APIs, implement deep linking and push notification flows, and add analytics through Mixpanel and Firebase.

I improved application startup performance by approximately 40% through code splitting, lazy loading, and profiling slow render paths with Flipper and Xcode Instruments. I migrated feature screens to the React Native New Architecture using Fabric and Turbo Modules to reduce bridge-layer bottlenecks.

I lead a mobile and web engineering team of more than five people. I introduced sprint workflows that reduced average delivery time by about 25%, while maintaining more than 95% code quality and on-time delivery. I also own architecture decisions, conduct code reviews, pair with developers, and run internal sessions on React Native performance and testing.

I helped ship 12 production applications across the team, including 10 published on the Google Play Store. Several applications achieved ratings above 4.5 stars, and delivered features contributed to approximately 40% growth in user engagement.

I established reusable React Native engineering patterns, including offline-first synchronization with SQLite, feature-level modularization, and a shared component library. These practices improved consistency and reduced duplicate fixes across projects.

I led client workshops with stakeholders in the United States and Australia, turning requirements into scoped features and realistic estimates. I also reviewed code, paired with developers, and delivered internal training on performance, Jest and React Native Testing Library patterns, and cross-platform debugging.

I built and released React Native features for client applications on iOS and Android, working from product specifications through Google Play Store delivery. I developed ownership of complete features while contributing to production mobile applications.

I created custom Android native modules in Kotlin and Java for video caching, content URI file-path resolution, and location permission handling. These modules addressed platform-specific needs that were not adequately covered by existing open-source packages.

I developed practical experience with SQLite-based offline-first storage, Jest testing, performance debugging, and production release workflows.
