I build the AI software,
and run the business it runs on.

Phill Sieg

Business development for a federal contractor — and the AI tools underneath it, built by hand.

Not an engineer. I ship into government compliance, one of the least forgiving places software can go. Here's the work, and what it's teaching me.

What I do

I've spent my career on the business side of federal programs — acquisition, program management, the unglamorous machinery that makes government actually deliver. For most of it, building software meant waiting on someone else.

That changed. AI now lets a domain expert build the tools they used to wait on a dev team for — and that quietly rewrites who gets to build software at all. I'm a test case for the idea, documenting it in the open.

Selected work
01

Federal contracting AI platform

A pre-award-to-post-award platform with 20 specialized AI agents that draft, review, and manage government contracts — checked live against FAR, DFARS, VAAR, and HHSAR rule sets. The work a team of analysts grinds through by hand, structured and accelerated.

02

AI acquisition trainer

A training simulator that coaches government acquisition staff through real procurement decisions — and never hands them the answer. It makes them reason their way to it. Most AI races to answer faster; this one is built to make you better without it.

03

A personal AI operating system

I run my work and my life on a heavily customized personal AI infrastructure — its own agents, voice, persistent memory, and automated workflows wired into how I actually operate. Built in the open, used every day. My clearest proof the operator-builder thing is real.

Also shipped: interax.app (a drug-interaction predictor, on the App Store), a weather-prediction app, and a pile of tools my kids actually use.

Writing

Building AI as a non-engineer, in public

I'm starting to write about what it actually takes to build AI software when you came up on the business side — what works, what's hype, and what shipping into a high-stakes domain demands that the demos never mention. New posts land on LinkedIn first.
