About me
Hi, I'm Kai, a UK senior full-stack engineer who builds practical AI into real products. As a founding engineer at a fintech, I built an FX product, payment SDKs used by 100+ merchants, and led my team's move to AI-assisted engineering with reusable AI tooling. Before that I led the NHS.UK React design system at NHS England, and I ran a Shopify store with custom automation. I build AI agents, LLM features and dev-team AI workflows that are reliable, secure and maintainable. I work one dedicated day a week, so please message me before ordering.
