"Architecting systems through Engineering Principles"
summary
Nubank runs 1100+ Clojure services for 15M+ customers and encodes reusable norms: microservice shape and continuous delivery, automated scaffolding for new services, and expectations like recalculate datasets daily and republishable events so backfills and retries are safe. Built tools include a schema catalog called suction contract catalog that cuts integration failures — about 80% of integration issues caught earlier — and a backend-driven UI compiler that speeds mobile iteration.
