Professional summary

Principal systems architect and hands-on engineering leader with 25+ years building production software across aviation, autonomous and edge systems, and consumer-scale platforms. Led a seven-engineer team delivering production software for business- aviation customers; now designs deterministic governance middleware for autonomous systems and agentic AI. Combines technical strategy, production implementation, safety and compliance thinking, and source-bound architecture, API, and product documentation.

Core expertise

  • Systems architecture: autonomous systems, agentic AI, AI governance, edge computing, distributed systems, event-driven architecture, resilience, fail-safe design
  • Architecture & delivery: technical strategy, reference architectures, API design, CI/CD, DevSecOps, TDD, SOLID, mentoring, and cross-functional delivery
  • Platforms & languages: Swift, SwiftUI, Combine, TypeScript, Node.js, Rust, AWS Lambda, Docker, GitHub Actions, PX4 SITL, MAVSDK, and MAVLink
  • Aviation & defense: UAS, FAA Part 107, proposed FAA Part 108 BVLOS, ISR, EMCON, GPS-denied operations, DO-178C awareness, and SOSA/MOSA

Professional experience

2026–Present
Principal Architect, Contract · Confidential AI Startup Architecting a multi-agent AI application using governed orchestration, agent runtimes, provenance systems, and reliability patterns for concurrent agent coordination. Translating ambiguous product goals into system boundaries, architecture decisions, and implementation-ready technical plans.
2025–Present
Principal Systems Architect / Founder · Flightworks Systems & Flightworks Aerial LLC Architected Flightworks Sentinel, vendor-agnostic governance middleware that separates AI proposals from autopilot authority through deterministic ALLOW, DENY, and ESCALATE verdicts. Designed pure-function policy evaluation, hash-chained evidence, comms-denied ISR governance, and compliance-first UAS mission procedures.
2025–Present
Open-Source Systems Architect / Technical Author · AgentVector & agentincommand.ai Created a deterministic AI-governance framework of Eleven Laws in four groups, implemented through Swift, TypeScript, and Rust enforcement kernels and verified by a shared Conformance Suite. Built Vigil and designed Light Station to make governed decisions inspectable.
2020–Mar 2025
Technical Team Lead / Architect · Aircraft Performance Group Led a seven-engineer team delivering production software for business-aviation customers. Owned architectural direction, modernized applications with SwiftUI and Combine, built CI/CD pipelines, and institutionalized TDD/SOLID practices and repeatable engineering standards.
2006–2020
Senior Software Engineer · Wayfair, MapQuest, AOL Progressive engineering roles across consumer-scale search optimization, geospatial and navigation systems, and mobile applications.
