I'm a father of 3 amazing children, that's the foundation everything else is built on. Professionally, my career started at the data accuracy level of systems people actually depend on.

Facebook first, I worked on SUMA, which was essentially about identifying when the same person was operating multiple accounts so ad impressions weren't being counted twice against the same IP. The work was simple in concept: advertisers were paying against numbers that didn't reflect reality, and that needed to be fixed. From there, Tesla, inside the Autopilot ML pipeline. The thing you learn fast in that environment is that the model is only as good as what you feed it. Bad input data doesn't produce bad reports. It produces bad decisions at speed. Then Apple, contributing to iOS 15 Maps, the 3D city experience and AR walking directions that launched September 2021. Street level imagery annotation. The whole point was accuracy: if the data doesn't match the real world, the AR directions point you the wrong way. Three different industries. Same problem from my vantange point. When the foundational level is off, everything built on top of it is off too. Payments is no different to me, merchants just can't always see it from the inside. A false decline looks like customer behavior. Approval rate leakage looks like normal variance. Routing that's leaving money behind looks like the cost of doing business. The data tells a different story. Most people just aren't reading it. That's what I do at com. Not selling infrastructure, finding where the data and the reality don't match, and showing merchants what it's actually costing them. Outside of work I'm basically co-building my fiancée's esthetics business, marketing strategy, systems, courses, content. I call myself her unofficial COO. Different industry, same thing: figure out what's broken and fix it. Fun fact: she's been in business for 5 years, served over 485 clients, and logged 2,166 appointments.
