Work

Selected work.

Three flagship case studies, plus other shipped work.

Professional work is intentionally written at a public-safe level: enough to show scope, ownership, and technical depth without exposing internal or sensitive program detail.

Flagship case studies

  1. Flagship · applied AI product

    2026 · Pre-Alpha · Cofounder & CTO

    Ledger / Vera

    A civic AI assistant where every claim cites its official source: Vera answers only from a closed set of grounded tools, and an un-sourced fact cannot be constructed in the type system. A federal data foundation built, with state-level coverage activating behind a fail-closed bar.

    • Next.js
    • TypeScript
    • Supabase
    • Anthropic API
    • Vitest
    • Playwright
  2. Flagship · independent systems

    2026 · Active build · Solo

    Milodex

    A solo-built autonomous trading system where every order clears a fail-closed risk chokepoint no code path can bypass: exactly-once execution drain, append-only event store, a 17-check veto layer, and CLI plus Qt desktop operator surfaces. Paper-only, enforced in code; governed by 58 ADRs and a custom Opus risk-reviewer.

    • Python
    • Alpaca
    • SQLite
    • Parquet
    • PySide6 / Qt
    • pytest
  3. Flagship · professional engineering

    2022 – present · Shipped & ongoing · public-safe

    Test Infrastructure at Boeing

    Mission-critical test infrastructure for a strategic defense guidance system, written public-safe. Three concurrent efforts spanning Ada, LabVIEW, hardware integration, and stakeholder-level systems work (one originated, one led, one built from scratch), plus internal frontier-AI adoption across two organizations.

    • Ada
    • C++
    • LabVIEW
    • Hardware integration
    • Requirements engineering

Additional shipped work.

  • MSM Awakening Tracker

    2026 · Shipped · six releases

    Personal project · desktop

    A Windows desktop companion app for My Singing Monsters, built solo from greenfield to six tagged releases. Production-grade reliability for a solo project: an atomic, threat-modeled auto-updater with SHA-256 verification and rollback, a two-database SQLite design whose user progress survives full content rebuilds, a self-publishing GitHub Actions pipeline, and a 505-test suite.
