Case study: how we built Kabuken
Engineering decisions behind our bilingual data platform on Japanese regulatory filings
We have published a case study on Kabuken, our platform for fundamental analysis of Japanese equities, built on EDINET XBRL filings.
It covers two engineering decisions in depth — auditing database indexes against real query patterns, and treating filings as history rather than a cache — and the spend ceiling that guards our own production jobs.
