01 — About
Build calmly. Ship thoughtfully.
I spend most of my time on systems that have to stay up: content platforms, subscription products, and the packages underneath them. At Macareux Digital I lead client delivery on Concrete CMS — core contributions, marketplace add-ons, SSO, and payment integrations for brands such as Rakuten, NTT Docomo, and Daily Portalz. Earlier I designed iOS app interfaces and built REST APIs at product studios in Tokyo and Dhaka. I like leaving a codebase easier to change than I found it.
