Keishin Nishiura

JavaScript, TypeScript, CSS, Python. Generalist across backend, frontend, and QA.

CSS container queries and the newer viewport APIs. Also poking at what LLM tooling can realistically automate in day-to-day client work.

Small automation tools — GitHub Actions pipelines, API mashups, and a weather notification bot.

Writing about CSS, responsive layout, and web tooling — guest posts welcome. Happy to talk about front-end work from a Japanese agency perspective.
