I build software. Currently Founder & CTO of Mantle. Side work lately is mostly LLM inference and agent infrastructure — what most of the recent posts here are about. Research background in computational physics and GPU-accelerated scientific computing — an early GPGPU practitioner from a decade before GPUs became the substrate of modern AI.

Previously: Senior Director of Engineering at Clio, co-founder of Evey Events (acquired 2022), and Director of Engineering at Shopify. M.Sc. Computer Science (computational), Memorial University.
