I'm a React Native developer who takes mobile products from architecture through to store release. I'm the sole mobile engineer on LawWorld, a production AI legal platform with 10,000+ registered advocates on Google Play, where I own authentication, access control, in-app purchases, real-time streaming, and offline behaviour. I'm comfortable working down to the native layer — custom Expo config plugins, TurboModules in Kotlin and Swift, EAS build pipelines, and OTA release management.

• 🏗️ Mobile Architecture & Ownership — Sole mobile engineer on a ~110-screen production app with 10,000+ registered advocates, owning mobile architecture, release engineering, and Play Store submission end to end alongside a 3-person backend team.
• 🔐 Two-Layer Access Control — Role-based permissions resolved against subscription-tier entitlements, designed so a malformed plan response degrades gracefully instead of stripping paying subscribers of purchased features.
• 🔄 Resilient Auth Layer — Eliminated unintended logouts on unstable networks with a centralized fetch layer that collapses concurrent token refreshes into a single in-flight request, guards against retry loops, and tolerates offline 401s.
• 💳 In-App Purchases — App-wide StoreKit provider so auto-renewals, "Ask to Buy" approvals, and post-outage redeliveries are never dropped — backing a 4-tier subscription group and consumable wallet top-ups with server-side receipt verification.
• 📝 Document Sync Engine — Snapshot-diffing sync between concurrent web and mobile editors with debounced batching and 413-safe chunking, surfacing a visible failure state instead of failing silently.
• 🌊 Token-by-Token AI Streaming — Replaced React Native's buffering fetch with SSE over expo/fetch; extended the pattern to WebSocket dictation and Socket.IO live transcription.
• 🚢 Release Engineering — Cut hotfix turnaround from a full store review cycle to a same-day push via EAS Update OTA; authored 7 Expo config plugins and maintain 4 EAS build profiles across Android and iOS.
• 🛡️ Privacy & Compliance — Network-layer AI-disclosure consent gate that blocks third-party AI requests before any user content leaves the device, satisfying Apple's App Store disclosure requirements.

Open-source React Native New Architecture TurboModule exposing live bandwidth and link-quality signals — replacing the binary online/offline flag most RN apps rely on.

• Native Bridging: Android NetworkCapabilities + iOS NWPathMonitor behind a codegen'd TypeScript spec, implemented in Kotlin and Swift.
• Production-Ready Packaging: Runnable example app, GitHub Actions CI, and semantic-versioned npm releases.

Rental and tenancy management app for independent landlords · React Native (Expo), TypeScript, Node.js, MongoDB.

• Offline-First Ledger: SQLite-backed rent ledger with an outbox sync queue — on-site entries reconcile on reconnect without double-posting a payment.
• Multi-Role Codebase: One app serving landlord and tenant roles via per-role navigation trees and server-driven entitlement checks.
• Landlord Tooling: Multi-property portfolios, lease document storage, auto-generated rent schedules, UPI collection with reminders, and maintenance-request threads.

• Deeper React Native New Architecture internals — Fabric, JSI, and custom TurboModule patterns.
• Hardening OTA release strategies with EAS Update channels and rollout gating.
• Offline-first sync patterns and conflict resolution for mobile-first products.
