Custom Shopify theme built with Liquid for épuis & co., the flower shop and gallery I co-own in Hakodate. Learning theme architecture — layouts, sections, snippets, and the rendering pipeline behind the role.

An incident-tracking and observability platform I built to simulate how a Resiliency/SRE team monitors, logs, and resolves live issues — tracks incidents end to end, visualizes system health with Grafana dashboards, and alerts the team in Slack when something breaks. Built in Rails 8 with Prometheus for metrics, Docker for deployment, and CI (Minitest, RuboCop, Brakeman) for code quality.

A Rails site built for TSU @ the table gallery, my family's space inside a 105-year-old warehouse that also houses our photo studio and flower shop. Active Storage handles the gallery's photography end to end.
