Hi — I'm Miller Bath.
I build payment systems and AI products.
Last year at PayIt, I joined the Payments Platform team to build and launch Payment Plans, a recurring-payments product projected to bring more than $400K in annual revenue online. Using Cursor and Claude Code, I delivered it four weeks ahead of schedule and added a sidecar lifecycle monitor that caught dozens of bugs before launch. Built with Java, Kafka, and MongoDB, the system has processed more than $15M, with plans to expand to more than nine clients.
After a successful launch with Harris County, I joined a newly formed AI product and tooling team. Working closely with a product manager, I added RAG prompt management to Smart Guide, enabling prompt versioning, A/B testing, and canary rollouts. I was then selected by our VP of Engineering to join an AI skunkworks team, where I built internal agents and a knowledge base to rethink parts of the software development lifecycle.
