John Fewell

Senior full-stack engineer in Toronto. Angular and TypeScript up front, Node and Python behind, seven years of production work. Many more years of working on my own stuff before that. The last year was at an AI-native SaaS company, shipping through spec-driven agent workflows with review and tests on every change.

Building

Slop Toronto: downtown Toronto in 3D in the browser, in three.js WebGPU and TSL on the engine of mrdoob's Slop New York. The TTC subway over the Bloor Viaduct, streetcars and GO trains on the real network, and the city's own street furniture from City of Toronto Open Data. Ride it live.
