Our tech stack

Our tech stack today consists of ReScript, TypeScript, JavaScript, React.js, Node.js, Postgres and Redis. We use GitHub for code and continuous integration to deploy to Kubernetes on Google Cloud Platform. We have a public REST API and our browser client uses a realtime WebSocket API. We obsess over details and quality of the user facing features and their implementation. Yet we move fast by creating focus and leveraging high quality foundations. ReScript, Melange and OCaml are some of the languages that get us excited which is why we’ve ventured into exploring ReScript in our frontend stack.
