About
I'm a software developer. I've spent the last 20+ years working across the spectrum from computational science to commerce platforms, mostly at the intersection of engineering and entrepreneurship — and increasingly back at the intersection of engineering and machine learning.
Now
These days I'm focused on Mantle, the company I founded in 2023. Mantle is a revenue operations and enablement platform for app builders — particularly those on Shopify, but increasingly for standalone SaaS too. The thesis is that app and SaaS companies all end up rebuilding the same growth and monetization plumbing, and there's a better way to do it.
Alongside Mantle, I spend a lot of cycles on LLM systems — particularly the boundary between inference efficiency and product capability. Recent experiments include Calibrated Sparse Attention (training-free attention pruning), cognit (hybrid Mamba+attention models with persistent session state), cevolve (evolutionary search over LLM-generated code), and unitask (unikernel-isolated agentic execution). Most of this lives on GitHub.
Research roots: GPGPU and early ML
My academic background is computational science and physics, and I worked on GPUs for scientific computing in the early GPGPU era — before GPUs became the substrate of modern ML/AI. My M.Sc. thesis, Efficient computational fluid dynamics methods for GPGPUs (Memorial University, 2010), used GPU parallelism to accelerate the solution of coupled nonlinear partial differential equations for fluid simulation. CUDA was a few years old, most scientific code was still CPU-bound, and the case for general-purpose GPU compute was very much still being made. AlexNet didn't land until two years after I defended.
In parallel I worked on a research assistantship at Memorial applying machine learning to medical imaging for cancer detection — also well before ML went mainstream. Two threads, same era: ML on one side, GPU-accelerated scientific computing on the other. They've since converged into the same thing, and most of my current side work is on that convergence.
Undergrad: a B.Sc. in Computer Science and a B.Sc. in Physics, both at Memorial. The physics side informs more of how I think about systems than the CV would suggest.
Before
Before Mantle I was a Senior Director of Engineering at Clio, the legal practice management platform, focused on mid-market firm products, permissions, and the public API and app ecosystem. Before that I co-founded Evey Events, a Shopify-based ticketing platform that was acquired in 2022. And before that I spent six years at Shopify as a Director of Engineering, working across merchant services — application security, fraud, payments, shipping.
