Hello!

James Coombs — Product Engineer

I use rigorous data, modern architecture, and smart automation to close the gap between what users need and what engineering ships.

Most platform engineering stops at the component library or the deployment pipeline. I focus on the whole loop: finding the user friction, defining the business metric, building the architectural fix, and proving it moved.

I build the infrastructure, developer tooling, and UI abstractions that allow teams to ship high-performance web experiences at scale.

Your AI Skills Have the Same Problem as Your CLAUDE.md. Here's the Data.

A controlled ablation, 42 runs: a behavioral-payload skill added zero marginal defect detection over a no-guidance control. A skill whose payload is documentation inherits documentation's 0%.

I Gave an AI Agent Unrestricted Shell Access. Here's What Happened Next.

Unrestricted shell access handed to an AI agent, then the defense-in-depth architecture that made it survivable: layered hooks, and the self-approval bypass patterns they had to close.

7,798 Components. Import One, Ship One.

T7,798 generated components in one package. The real cost of the barrel file is not bundle size (it tree-shakes fine), it is build-time parse, plus a dual type-resolution trap that runs but will not type-check.
