What I Do

How I build mobile products

React Native at the core, AI and security as differentiators, and backend depth underneath — four strengths that work together, not in isolation.

React Native Platform Engineering

Production mobile apps and the architecture behind them — releases, performance, native integrations, and end-to-end feature ownership across iOS and Android.

Shipping fast, stable React Native apps — and leading the platform they run on.

ArchitecturePerformanceNative ModulesApp Store Releases

AI-Powered Mobile Experiences

LLM features, conversational interfaces, and personalized AI workflows designed to feel native on mobile — intelligent product experiences, not bolted-on chatbots.

Bringing AI into mobile products in ways that feel native, fast, and trustworthy.

LLM IntegrationConversational UIRAGAI Product UX

Security-Focused Application Architecture

Authentication, privacy, and data protection designed in from the start — secure backend integration and the AI-security considerations modern mobile apps demand.

A cybersecurity background applied to the way mobile apps store, move, and protect data.

Backend & Platform Systems

The backend and platform depth that makes great mobile products possible — Go, Node.js, PostgreSQL, APIs, queues, observability, and cloud infrastructure.

Understanding the systems behind the app — so the mobile experience holds up at scale.

Mobile is the product; AI makes it intelligent; security makes it trustworthy; backend depth makes it hold up at scale.

Featured Work

Production mobile case studies

Real apps shipped to real users — built end-to-end, from the React Native client to the AI and backend systems behind it.

NestleAI

AI-Powered Parenting Companion · iOS & Android

A production React Native (Expo) app: an AI 'co-parent' for new parents. Offline-first baby-care tracking wrapped around a personality-driven AI companion — shipped to both app stores. Built end-to-end as the founding engineer.

NestleAI — Backend & AI Platform

AI & Backend Platform · Node.js

The intelligence layer behind the NestleAI app: a modular Node.js/TypeScript backend powering real-time AI conversations, safety guardrails, 15+ background worker queues, and a layered AI pipeline — built safety-first for an infant-care domain.

SentinelRN

Runtime Integrity & AI Security SDK · React Native

An open-source security SDK that answers the question most mobile security libraries leave unanswered: "can I trust this environment enough to perform this action?" It detects compromised runtimes (root, jailbreak, emulators, hooking, tampering) and inspects AI-bound input for secrets, PII, and prompt injection — returning structured, explainable threat reports instead of bare booleans. Built end-to-end as creator and sole engineer.

What I owned
· Trust core: risk scoring & policy engine· AI subsystem: secret/PII/injection detection
Engineering focus
· One noisy-OR risk engine for every signal· Fail-open — a detector crash is never an app crash

Media Learning App

Offline-First Audio/Video Platform · iOS & Android

A mature cross-platform learning app that streams long-form audio and video, downloads for offline playback, and resumes where you left off. I led a ground-up rewrite of the playback engine for offline-first reliability and a major framework upgrade of the underlying codebase — anonymized engineering case study.
