// about

Hi, I’m Steven. I like building things and figuring out the tricky problems along the way.

Steven Boyle
~/me.jpgNewcastle upon Tyne, UK

I've spent the last decade building software for the web, growing from IC to leading engineering teams and owning the whole path from architecture to delivery. I enjoy working hands-on with customers, from the first technical conversation through to launch and beyond.

I care about how software feels at every end of it: the developer experience of the team building it, the agent experience of the AI working alongside them, and the user experience of the people relying on it. Lately that means agentic engineering, shipping at pace with AI without dropping the quality bar.

A static Next.js site whose hero is a WebGPU agent swarm, simulated on the GPU with vgpu.

TypeScript / Next.js / React / WebGPU / WGSL / vgpu / RSS

4 highlights
  • Agent swarm simulated in WGSL compute shaders, rendered as instanced SDF robots
  • GPU → CPU feedback for live telemetry: agents, crews working, tasks done
  • Medium posts pulled from the RSS feed at build time and rendered as native pages, with a committed snapshot that keeps older posts and builds working if Medium is down
  • ⌘K command palette, git-graph timeline, static export with no server at runtime
