🚀 Flagship Projects

A production dating and social platform for sapphic women — live on both app stores, 16 languages, a self-hosted trust & safety ML pipeline, and ~250,000 lines of Dart. Designed, built, and operated solo.

Tech Stack: Flutter, Cloudflare Workers, Hono, Durable Objects, Neon (PostgreSQL/PostGIS), Cloudflare R2 · Status: Live in App Store and Google Play

A local-first AI companion app — every conversation runs entirely on-device through a fine-tuned Gemma 4 model via llama.cpp/Metal, so no data ever leaves the phone.

Tech Stack: Flutter, GGUF/llama.cpp, custom LLM fine-tuning pipeline · Status: iOS-first, active development

An e-commerce and logistics platform for a sustainable family orchard, covering the full lifecycle from inventory to fulfillment.

Tech Stack: React, TypeScript, Tailwind CSS, Supabase, Stripe API · Key Features: Secure payment processing, admin dashboard for order tracking, dynamic seasonal inventory

🧭 How I Work: Collaborative AI Engineering

I partner with AI agents to architect and execute complex systems — I own the system design, data modeling, and infrastructure decisions; the AI handles scaffolding and execution at speed. It's how one engineer ships and operates four production applications at once. See WHY-THIS-STACK.md for the reasoning behind each project's tech choices.

Solo-built doesn't mean solo-process. Every non-trivial change goes through the same discipline a team would enforce: PR review before merge, documented architecture decisions before implementation, and staged rollouts behind feature flags so nothing risky ships straight to production users.

Outside of Utopian Creations, I run real-time technical operations for Zoox's autonomous vehicle fleet — coordinating live incident response across Teleoperations, Fleet Response, and Rider Operations, diagnosing faults, and directing recovery over CLI protocols. That's the muscle for working inside someone else's process under pressure, not just my own.
