MINDWISE grew out of Track4: a real-time threat-intelligence platform protecting cardholder exposure across a portfolio of U.S. financial institutions and major payment processors. I co-founded it and ran engineering as CTO.
I hired and led a team of four engineers from initial idea through enterprise rollout, and personally wrote the core ingestion service in Node.js: concurrent scrapers that captured darknet market listings as they were posted and flagged compromised cards within minutes.
The work I’m best known for there is identifying the point of compromise in the Jason’s Deli breach by clustering 170,000+ stolen cards from Joker’s Stash against merchant-location data. The methodology and visualizations were published by Krebs on Security.
We integrated LexisNexis for high-confidence identity resolution, which turned partial cardholder data into actionable intel, and the early detection prevented significant fraud losses for Golden 1 Credit Union.
We were also an operational partner to the U.S. Postal Service Cybercrime Unit, and built vendor-attribution systems out of shipping analytics and geospatial triangulation to support federal investigations. More on the platform itself is on the projects page.
