LoveNotes
End-to-End Product

LoveNotes

SMS-first micro-ritual helping couples stay connected through daily appreciation prompts and weekly LoveLetters. Core insight: couples drift apart not from lack of love, but from lack of consistent low-friction connection rituals. Designed habit-forming system grounded in Gottman research (5:1 appreciation ratio). Built full stack: React + Supabase + Twilio + Stripe + Gemini AI. Now serving 11 beta couples with 80-90% engagement rate. Led end-to-end product development from user research and PRD through launch, iteration, and growth.

Agent Chat

Local-first, Slack-style interface for orchestrating multiple Claude Code AI agents simultaneously. Built as a single-page web app with no build step, connecting to a Python bridge server that spawns Claude CLI subprocesses via PTY. Each agent runs in its own terminal session with full context persistence, while the UI provides real-time streaming output, status indicators, and a notification system for structured JSON reports. Architecture prioritizes simplicity—SQLite for persistence, WebSockets for live updates, vanilla HTML/CSS/JS frontend. A lightweight control plane for running parallel AI coding sessions.
