Stephen Sweeney

Principal systems architect · Monument, CO

25+ years building software systems — and arguing that when an AI agent acts, command has to be architectural, not behavioral.

Professional focus

I work where architecture, operational authority, and evidence must agree. The public argument for that work is on this site: the Agency Paradox, the AgentVector Codex, and the reference implementations under Field Operations. I am open to architecture, technical leadership, and governed-autonomy work.

Experience

Career details below are drawn from the current résumé. Confidential client work is described only at the level cleared for publication.

2026–Present
Flightworks Systems Principal Systems Architect · Flightworks Sentinel Designing vendor-agnostic deterministic governance middleware between AI proposal modules and autonomous flight control, with three-state authority gating and hash-chained evidence for deterministic replay.
2020–Mar 2025
Aircraft Performance Group Technical Team Lead / Architect Led a seven-engineer team delivering production software for business-aviation customers. Owned architectural direction, drove SwiftUI/Combine modernization, built CI/CD pipelines, and strengthened release quality through repeatable engineering standards.
2025–Present
Flightworks Aerial LLC Founder / Pilot in Command · FAA Part 107 Founded a drone services and technology company for end-to-end UAS mission execution with systems-minded procedures and compliance-first operations.
2006–2020
Wayfair · MapQuest · AOL Senior Software Engineer Progressive engineering roles across consumer-scale search optimization, geospatial and navigation systems, and mobile applications.

Selected systems

  • Production aviation software (Aircraft Performance Group) — technical leadership, application modernization, CI/CD, and delivery across mobile and cloud surfaces.
  • Flightworks Sentinel — deterministic governance middleware for trusted UAS autonomy; active development.
  • AgentVector — open-source constitutional governance framework and the source of the documentation system presented on this site.

Current work

Independent work spans the AgentVector governance framework, Flightworks Sentinel, Part 107 operations, and a confidential multi-agent software engagement. These are current projects, not prior-employer products.

  • Flightworks Systems — deterministic governance for autonomous aviation
  • AgentVector — constitutional governance research and open-source documentation
  • Multi-agent platform — governed orchestration, provenance, and reliability patterns for a confidential startup engagement
  • Vigil / Light Station — desktop-agent governance reference implementations
