Engineer — software, systems & design · Austin, Texas
Building software one careful step at a time.
I like navigating complexity on mountains, through systems, and wherever technology meets people.
About
Shaped by wild places. Built for people, with care.
I’m Marin — from Japan, by way of a few places, now based in Austin. Climbing, sailing, and diving shaped how I approach technology: prepare carefully, stay curious, and never lose sight of the people it’s for.

How this site is built
This site is my current project — designed, built, tested and maintained end to end.
Source
Static first, by design
Astro and strict TypeScript, with design tokens and one typeface each for statements, prose and metadata.
Checks
One command before every change
Formatting, linting, types, unit and end-to-end tests, plus automated accessibility checks targeting WCAG 2.2 AA, in light and dark. CI runs them again, and nothing ships unless they pass.
Build
Plain HTML out
Every page is rendered ahead of time, including the summit ridge, drawn from real elevations. Just a few small scripts.
Ship
Deployed to AWS
Every push to main deploys itself once the checks pass: GitHub Actions with short-lived credentials, to S3 behind CloudFront.
Visitors
Fast, accessible, private
Works by keyboard, respects reduced motion, and there are no analytics, cookies or trackers.
Planned
Health you can check
Deploy history, test results, accessibility and performance scores, and uptime, published here.
