Senior React Native Developer
Led 3+ production apps (Spin, Buzzmi, Gifter) from architecture to store release — owning code signing, provisioning, TestFlight beta, and staged rollouts — cutting time-to-ship for new releases.. Extended the SPiN platform to a Vue 3 + Capacitor codebase, shipping to iOS, Android, and Web from a single build with native Sign in with Apple/Google, push notifications, and over-the-air updates.. Shipped a true write-once cross-platform product on React Native Web, styled with a Tailwind CSS (NativeWind) design system shared across iOS, Android, and Web.. Accelerated feature delivery∼30% by integrating AI coding tools (Claude, ChatGPT, Perplexity, Copilot) into the daily workflow for scaffolding, refactoring, test generation, and code review.. Cut UI development time ∼30% across projects by architecting a reusable, typed component library that standardized design tokens and eliminated duplicated screen code.. Delivered sub-second live updates for messaging and live sports data by integrating the Stream Chat SDK and WebSocket connections with reconnection and backpressure handling.. Reduced manual build-and-distribution effort over 50% by designing GitHub Actions + EAS CI/CD pipelines that automated builds, signing, and store submission on every merge.. Improved perceived load times and cut redundant network traffic by migrating data fetching to RTK Query and React Query with request de-duplication and cache invalidation.. Shipped subscription revenue features by implementing Stripe and PayPal in-app purchase and billing flows with secure server-side verification.. Established automated testing with Jest/Vitest unit suites and Playwright/Detox E2E, wired into CI to gate every merge, and raised team quality by mentoring junior developers and setting code-review standards.

Reduced crash rate ∼40% and stabilized frame rates across 2 production apps by profiling and resolving critical memory leaks in list rendering and event listeners, using Sentry and Firebase Crashlytics to triage the worst offenders.. Made complex async flows predictable — authentication, notifications, and paginated feeds — by architecting Redux-Saga side-effect handling with cancellation and retry.. Lifted user re-engagement by implementing Firebase Cloud Messaging (FCM) push notifications with deep-linking into relevant screens.. Improved onboarding conversion by integrating Google Maps, social login (Google, Facebook), and in-app purchase flows into a streamlined signup path.. Accelerated cross-team delivery by creating and documenting scalable, reusable UI components adopted across multiple product teams.
React Native Developer
Earned positive client feedback on design fidelity by delivering pixel-perfect UIs with smooth 60 fps animations for 2 client applications.. Enabled auth, real-time sync, push, and analytics for client apps by integrating the full Firebase suite.. Shipped geolocation, navigation, and tracking features by integrating Google Maps and Mapbox.. Reduced new-developer onboarding time by establishing a modular, clean codebase structure and conventions.
