Hi, I'm Michael Fein.

Building AI inference systems across silicon, systems, and software.

I lead Frontiers at Etched, working across inference and chip architecture for transformer inference ASICs. I translate customer workloads into product requirements, weigh tradeoffs across compute density, memory hierarchy, interconnect, and power, and build the technical and commercial partnerships needed to bring new systems to market.

Much of my time goes to performance and cost modeling, benchmarking against GPU baselines, and the inference software stack that customers deploy in production. I work closely with architecture, hardware, and software leads to set priorities, resolve dependencies, and build the teams needed to deliver.

Previously, I worked in McKinsey's Semiconductors and Industrials practice and at Citadel Securities. I hold an MS in Computer Science and a BA in Statistics from Harvard, where I taught probability as a teaching fellow.
