I'm a Microsoft Data & AI Engineer at KPMG Netherlands, focused on Microsoft Fabric, real-time intelligence, and operations research in the cloud. At FabCon Atlanta, I presented the first version of FleetPulse: a real-time fleet routing and optimization platform built natively on Fabric. It's an ongoing project, and the direction I'm most excited about is where live geospatial data and serious optimization tooling meet inside Fabric, rather than living in external services.

My broader work spans global banking M&A data platforms, graph-theory-based network topology automation for IoT analytics, and NLP pipelines for sensitive healthcare data. I'm particularly drawn to problems where the data engineering and the decision layer need to sit side by side, which is what pulled me toward real-time systems and operations research in the first place.

Kody Hartlaub is an internationally recognized performance specialist in the mental architecture of champions. He works exclusively with elite athletes, Olympic contenders, world-class competitors,
and high-performing organizations—including professional athletes on the Philadelphia Phillies, world champions pursuing their next title, Olympic-stage athletes, Division 1 programs, and corporations like L'Oréal—to unlock performance at the highest level.
In less than a decade, Kody has executed a complete program turnaround at the college level, taking a Division 3 athletic program from last place to top-tier status in under a year. He's guided a two-
time world champion through his pursuit of a third championship. He's positioned Olympic-level athletes for international competition. He's embedded himself in locker rooms and boardrooms where the margin of error is zero, and results are the only currency that matters.
His work is about diagnosis and execution. Kody identifies the psychological architecture underneath performance: the belief systems, decision-making patterns, emotional regulation, and mental discipline that separate champions from competitors. He rebuilds that architecture from the foundation up, then ensures it performs under pressure, when it counts most.
Kody holds a bachelor's degree in psychology and is completing his master's in sport performance and psychology. More importantly, he is personally mentored by Ben Newman, one of the five most respected performance coaches in the world. He has been selected as a judge for the International Globee Awards for Excellence: a distinction reserved for the elite practitioners in his field.
As founder of KHP Coaching, creator of the Diamond Leadership Architecture framework, and architect of the KHP1 performance community, Kody doesn't build athletes. He builds champions who know exactly who they are, what they're capable of, and how to deliver it when the stakes are highest
