Pouyan Jahangiri

I'm an AI architect and founder who came to software from physics. I'm joining Caterpillar as Senior Principal Architect for AI and ML, I lead Data & AI at fenel, and I founded MedBrain Technologies to bring agentic AI to clinical data. For over a decade I've shipped production ML in e-commerce and pharma, most recently leading 20+ engineers. Today I design agentic systems and the parts that make them trustworthy: evaluation, retrieval, and the data platforms underneath. My PhD at UBC modeled medical cyclotron targets at TRIUMF, and I still work like a modeler: start from first principles, then check the numbers. I also work where software meets hardware: at Aeris I built gas-sensing devices, their firmware and telemetry, and a cloud solver that pinpoints leaks, and I run local models and edge AI where there is no data center to lean on.
