Engineering Leader & Fractional CTO
I run a SaaS company's engineering with a team of AI developer agents, and I built the system that keeps them under control.
Open to remote leadership roles: part-time, fractional, or full-time.
Let's TalkAbout Me
I run a SaaS company's entire engineering function with a team of AI developer agents, and I built the system that keeps them under control.
That system is Foundry, an open-source GitHub Action I created at JoYnt. A human comments "@foundry go" on an issue, an agent works in an isolated branch, Foundry runs lint, typecheck, build, and tests, and nothing becomes a pull request until it passes. Merging always stays a human decision, and every step is recorded on GitHub.
The idea behind it is the same one that has run through my whole career: move fast inside hard constraints, and make the controls visible.
At INTL FCStone I led transactional data exchange, building the routing, reconciliation, and Dodd-Frank large-trader reporting layer the firm used to keep pace with new regulation, and before and after that I built and ran high-frequency trading platforms in futures and options.
As Director of Software Engineering at Epsilon (Conversant), I led the Ad Server API team shipping systems that ran on thousands of nodes across data centers worldwide.
Since 2019 I've co-owned Perception Farms, a licensed cannabis operator in Chicago now expanding into Minnesota, where I handle licensing, compliance, and technology across two state regimes. I hold an M.S. in Quantitative Finance from the Illinois Institute of Technology.
I'm open to remote leadership work, part-time, fractional, or full-time: director or head of engineering, fractional CTO, AI engineering enablement, and RegTech, FinTech, or other compliance-heavy platforms. If your team is figuring out how to let agents write code you'd actually ship, let's talk.
