SUM M AR Y
React and React Native developer with experience building production mobile apps from scratch through to release.
Comfortable in both Expo and bare workflow, with hands-on experience writing native modules for iOS and Android
when the JS layer isn't enough. Worked on a TikTok-style health video platform, WebView-heavy apps, and standard
React web projects. Used to working independently across the full cycle — from understanding requirements to
deploying and handing off.

• Built and maintained React Native mobile applications in a bare workflow environment, covering the full
development cycle from feature planning to App Store / Play Store release.
• Developed a short-form vertical video feed (TikTok/Reels-style) using FlashList with a custom player manager —
handles preloading of adjacent items and auto-pauses off-screen players to keep CPU and memory usage low.
• Integrated Banuba Video Editor SDK on iOS and Android: set up licensing, wrote the native bridge, and exposed AR
filters, real-time effects, and multi-track editing to the JavaScript layer.
• Built a WebView shell with runtime inject-script layer — patches the embedded web environment at load time
(DOM manipulation, event interception, API overrides) and communicates back through a type-safe postMessage
bridge.
• Wrote custom native modules in Swift (iOS) and Kotlin (Android) for secure storage, biometric authentication, and
background task scheduling; used JSI for synchronous calls on latency-sensitive paths.
• Worked on React web projects using Next.js and TypeScript — component architecture, API integration,
performance optimisation.
PR OJE CTS
Social Media Platform — Vertical Video
• Full-featured React Native app with infinite vertical video feed. FlashList + custom player manager with preloading
and auto-pause for off-screen items.
• Banuba SDK integration for in-app recording with AR effects and multi-track editing. Handled SDK config, licensing,
and the iOS/Android-to-JS bridge.
• Fluid swipe transitions and interaction animations with Reanimated 3 + Gesture Handler. Firebase backend for
media storage and real-time feed ranking.

React Native WebView & Native Module Platform
• Bare RN app with deep WebView integration — runtime inject-script layer that patches DOM, intercepts events,
and overrides APIs in the embedded web environment.
• Type-safe postMessage bridge for bidirectional communication between native shell and web content (auth
tokens, UI state sync).
• Custom native modules (Swift / Kotlin) for secure storage, biometrics, and background scheduling. JSI-based sync
calls for latency-critical paths.

Fitness Tracker App
• React Native app for logging workouts, tracking personal records, and visualising progress over time. Built with
Expo, Zustand for state, and React Native Charts Wrapper for graphs.
• Local-first architecture using SQLite — all data persists on device without requiring an account. Optional Firebase
sync for multi-device support.
• Custom animated progress rings and calendar heatmap built with Reanimated 3 for smooth 60fps rendering.

E-Commerce Platform
• Next.js / React / TailwindCSS storefront with shopping cart, product filtering, and Stripe checkout.

Task Manager App
• Full-stack task management tool — React frontend, Node.js/Express API, MongoDB, JWT auth. Deployed on Vercel
+ Heroku.
