SAFETY-CRITICAL SOFTWARE ENGINEER → AI SYSTEMS BUILDER

Twenty-five years designing and certifying software that isn't allowed to fail, now applying that same discipline to building AI agents, automation platforms, and full-stack systems for small businesses.

Background

Two disciplines, one habit of mind

The thread running through both halves of this career is the same: build systems that behave correctly under pressure, prove it, and don't ship what you can't verify.

Track A — Aerospace & Embedded

Safety-critical software, certified

Two and a half decades in aerospace and embedded software engineering, spanning flight control, fuel control, brake control, and hydraulics control software, inside CMMI Level 3 process environments. As Head of the Software Central Organization at Parker Hannifin Aerospace, directed certification audit readiness across five authorities: the FAA, EASA, Transport Canada, ANAC Brazil, and CAAC China, and led and mentored a software organization of 80+ engineers across multiple concurrent programs at global locations. Earlier roles built the foundation this later work stood on: Software Program Manager at GE Healthcare, Senior Software Engineer / Software Release Manager at Motorola, and Software Design Engineer at Federal Signal Corporation.

  • DO-178B/C compliance and certification methodology
  • Multi-authority audit leadership (FAA, EASA, Transport Canada, ANAC, CAAC)
  • Flight control, fuel control, brake control, and hydraulics control systems
Track B — AI & Automation

The same rigor, applied to AI

Now building AI agents, voice and chat systems, and full-stack automation platforms for small and mid-sized businesses through Digital Synergies — working as an expert in GoHighLevel, the core platform behind most of these builds. The engineering habits carry over directly: spec it, verify it, don't trust it until it's tested — now applied to agentic coding workflows and human-in-the-loop AI development.

  • Agentic coding with Claude Code, write→run→fix loops with decision-point review
  • Full-stack builds: Python, Flask, PostgreSQL, Railway deployments
  • Voice and chat AI agents on GoHighLevel and Twilio Studio
