I build production mobile systems — and I’m looking for long-term tech partners and founders who want to create something meaningful together. Six-plus years shipping React Native products with offline-first architecture, realtime systems, and on-device AI. Through MobileDevSimplified I bring senior technical ownership, calm judgment, and a bias for products that hold up in the real world.

Meaningful builds

Systems I’m proud of

Products I build and systems I’ve owned — privacy-preserving AI, realtime social, local marketplaces, and workflows that hold up in production.

Translate anywhere — even offline

Tulk

Shipped a fully offline iOS translator powered by Meta’s NLLB-200 model running entirely on-device via ONNX (~1.3 GB, 200+ languages).
Built chat, face-to-face split-screen, and voice in/out modes that work with no network after one download.
Designed for privacy by default — local inference, no accounts, no telemetry; live on the App Store.

Meet new friends, nearby

Hablo

Built a location-aware social app: discover people and places on map/list, check in with intent, and start realtime 1:1 chats.
Shipped React Native + Expo with Supabase (Auth, Realtime, PostGIS), TanStack Query, and MMKV — live on Google Play and the App Store.
Focused on trust and safety: blocking, reporting, full account deletion, and privacy-forward discovery.

Physical books. Local readers. Real handoffs

LetsRead

Built a neighbourhood book-sharing marketplace — list free or low-price physical books, discover nearby, chat to arrange pickup.
Live on App Store and Google Play with 100K+ Play downloads and multi-language support.
Product craft around distance-sorted discovery, Voice Capsules, and local handoffs — not an e-reader.

Deep work, gamified

Circa

Shipped a focus timer and habit tracker that turns deep work into streaks users want to keep.
Cross-platform React Native product owned end to end — from UX loops to store-ready delivery.

Shared tasks without the “did you do it?”

PingDo

Building closed-loop coordination for couples, roommates, and small trusted groups — assignment, explicit acceptance, completion, and handoff.
Designing realtime task ownership, Anyone claims, Pings, quiet hours, recurrence, and take-turns rotation for iOS and Android.
Private by default: invite-only Spaces, no public feed, no ads, and no cross-app tracking.

Offline AI medical translation

SAID Translations

Built an offline on-device AI translation system using Qwen and Meta NLLB.
Kept sensitive medical data private — no cloud dependency for core processing.
Optimized mobile inference for low-connectivity environments.

AI legal billing automation

Lawgbook

Designed a FastAPI ingestion pipeline for activity from meetings, calls, and communication tools via OAuth webhooks.
Built an LLM classification engine mapping unstructured activity to legal entities — clients, matters, billing categories.
Ran a multi-provider LLM architecture with OpenRouter and OpenCode, including tracing and observability.

Web3 fan engagement

LOOT8

Built mobile features for blockchain authentication and smart contracts.
Shipped scalable React Native experiences for digital identity and engagement.
