My team have 7 people distributed across the globe. 1 in Texas, 2 in bay area and a few folks in Quebec.
We've been working with clojure/java/react/typescript.
We have built a lot of systems, for products catalog management, orders management, customer arrival detection, customer support tooling, among others. We migrated from aws to google cloud.
Clojure was the main lang we used, but we also worked with python, nodejs, some Go.
