About Me

I build mobile products end to end: native iOS in Swift and SwiftUI, cross-platform apps in React Native, web in Next.js, and the AI backends behind them. Lately most of my work runs a language model somewhere in the loop, on the device where it can and in the cloud where it must.

  • Founding Engineer at Contextual Intelligence (formerly Luna Social), a social app with an iMessage agent behind it
  • M.S. Computer Science, Pace University, with a focus on HCI and mobile development
  • Building Life OS, a personal health app that reasons over Apple Watch, Whoop and Renpho data on device
  • Off the clock: guitar, film photography

Featured Projects

Life OS

One app for every signal you already wear and carry

Pulls Apple Watch, iPhone, Whoop and Renpho data into a single daily picture, then uses Apple's on-device Foundation Models to say what is working and what is not. Local-first with a Supabase sync layer and a cloud coach for the questions the phone cannot answer alone.

Stack: Swift 6 · SwiftUI · Foundation Models · HealthKit · AVAudioEngine · Supabase · Cloud Run · Claude API

Astra

Vedic astrology readings with the math done by code, not the model

A Next.js API and a native Swift client. Dosha and transit detection is deterministic; Claude only writes the reading. Twice-daily readings arrive over APNs on the user's own clock, prompts are split for cache reuse, and follow-up questions are generated on device by Apple Intelligence so a reading never leaves the phone.

#ios #full-stack #llm #private

Sleep tracking with adaptive soundscapes, iPhone and Apple Watch

Real-time audio built on an AVAudioEngine node graph with synthesized PCM, running in the background through the night. Watch biometrics arrive over WatchConnectivity, a sleep-stage classifier turns them into stages, and sessions sync to Supabase.

Where should a restaurant open next? Ask the order data.

Hackathon build on Knot's Transaction Link. Diners connect DoorDash and Uber Eats for rewards; operators see a demand heatmap of what people already order in areas nobody serves. Live demo · Walkthrough

Contextual Intelligence (iOS)

Leading the native SwiftUI app at work

End-to-end ownership of a production social app: architecture, media playback and caching, Combine pipelines, UIKit bridging where SwiftUI runs out, and performance work across a 500-file codebase with a 15-person history.

Stack: Swift · SwiftUI · Combine · AVFoundation · Firebase

#ios #swiftui #work

Luna Agents

An agent that lives in iMessage

Backend for Clo, the Contextual Intelligence assistant. iMessage webhooks flow through deterministic handlers for consent and RSVPs, then into a LangGraph agent with tools for reservations, events, people matching and rides. Background workers handle proactive outreach and profile embeddings.

Stack: Python · FastAPI · LangGraph · Gemini · Redis · Firestore · Composio
