From building e-commerce sites, mainly with Shopify, to ongoing improvements and operational support — I can handle just about anything, including advanced customizations such as custom apps beyond theme work.
I develop Shopify apps as my own original products. On July 13, 2026, I released Kirarity Custom Shipping, a Shopify app for customizing shipping rates, optimized for Japan and its many remote islands.

Broad support for putting AI to work — from introducing AI coding tools such as Claude Code to embedding AI features into e-commerce sites and websites. I also build RAG-powered AI agents and automate routine tasks, such as Shopify marketing reports, with Claude and Google Apps Script.
Building, improving, and operating websites on a modern stack combining Sanity as a headless CMS with Astro and Cloudflare — I can handle just about anything. This site itself is built the same way.
