About

Systems thinker.
Platform builder.

I'm a Staff Software Engineer with a decade of experience building production systems that operate at global scale. My work spans Android platform engineering, autonomous AI tooling, and distributed infrastructure — with a consistent track record of shipping complex, high-stakes programs on time.

I led technical programs at Meta / Instagram on a 2B+ user platform, built crash detection infrastructure saving an estimated $50M per year, and technical-led the feature that drove 180M new user acquisitions in a single quarter.

My recent engineering focus spans autonomous AI developer tooling — multi-agent systems that coordinate, verify each other's work, and run reliably without constant supervision — alongside deep Android platform instrumentation and cloud-scale mobile test infrastructure.

"The best engineers don't just write code — they build systems that outlive them."

Harvey AI LLC · Live on the App Store

A full AI fitness coach, shipped end-to-end and live on the App Store: chat-first coaching, photo-based meal logging with instant calorie estimation, and a 0–100 Physique Score that scans your progress and hands you the next step. Built on SwiftUI + Supabase with a Gemini-powered coaching engine, StoreKit billing, and an automated QA + self-improvement loop. The v3.1 release adds a native Apple Watch app — Today protocol, quick-log, Physique Score, and a watch-face complication — bundled right inside the iOS app.

Oracle Protocol
Harvey AI LLC · Autonomous AI Systems

Autonomous multi-agent coding framework with a four-tier hierarchy: Oracle → Manager → Lead → Coder. Each layer operates with phase-gated execution — agents can't advance without presenting evidence of completion. A SQLite-backed code knowledge graph over the entire Python source tree lets agents reason about cross-file dependencies and promote learning across runs. Resumable workflows survive session failures. Resolved three classes of deep reliability bugs: runaway self-recursion in agent spawning, inter-agent communication deadlocks, and venv bootstrap failures — making fully autonomous, unsupervised coding runs reliably production-safe.

Zoomable production map of a large-scale mail application — 134 screens, 220 navigation edges — derived from instrumentation source code rather than hand-drawn diagrams. Won an internal A/B test against the legacy tool and shipped to production. Includes static-analysis parsers (Compose wireframe extraction, ScreenGraph parsing, Android manifest deep-link resolution, Flux navigation extraction) and a live emulator capture engine that drives the UI over ADB, self-heals from ANRs, and verifies captures against element inventories.
