Just-Tech AI (JTAI) is an AI-powered legal document intelligence platform that Roman Slack solo-built from the ground up. As Lead AI Platform Engineer at Just-Tech LLC, he took the product from zero to a working, client-facing system serving the legal sector, owning every layer of the stack himself — the frontend, the backend, the cloud infrastructure, and the deployment.
Branded "JT AI — AI-Powered Legal Document Intelligence," the platform applies machine learning and large language models to process, understand, and analyze legal documents. It was built in close, direct collaboration with real clients — including the New York State Bar Association and numerous state legal service leaders — deployed to over 60,000 users with more than $130,000 in sales generated.
Roman Slack architected and operated the entire system single-handedly, integrating Google Cloud and Azure for a scalable, performant, production-grade backend. JTAI stands as an end-to-end legal-AI product owned solo from concept through infrastructure, engineering, and client delivery — a complete platform shipped by one engineer.
