Engineering
System design, integration, software architecture, testing, and the practical discipline of making complicated things work together.
where ideas are made
An independent engineering and creative initiative by Todd Hahn, bringing human imagination and AI collaboration to software, simulation, and music.

FEATURED WORK
flight trAIner
An AI-assisted flight training experiment.
What began as a question about learning to fly has become a hands-on exploration of AI engineering, simulation, architecture, and conversational instruction.

SIM COMPANION / WORKING PROTOTYPE
Giving a flight simulator a voice.
Sim Companion is a practical AI voice companion for Microsoft Flight Simulator. The working prototype explores spoken interaction, aircraft telemetry, and physical push-to-talk controls. Live simulator validation remains in progress.
Along the way, the project has become a testbed for voice interaction, responsiveness, reliability, and the practical costs of conversational AI.
Explore Sim CompanionTHE IDEA
Thirty years of engineering. A new medium.
I've spent more than three decades learning how to turn ambiguous problems into systems that work. Today I'm applying that foundation to AI engineering—not by leaving software engineering behind, but by extending it.
I own the vision, product direction, requirements, architecture, testing, and final decisions. ChatGPT and Codex contribute technical reasoning, implementation, and development assistance. The work is a collaboration guided and reviewed by me.More about how I build.
WHAT I'M BUILDING WITH
AI
LLMs, context, conversational design, local AI, agentic development, and the emerging practices around building software with intelligent systems.
Creativity
Music, composition, simulation, and technology as a medium for making something that did not exist before.

This is where some of mine are made.
