Clojure is our main language for building out both the web service that powers the user interface of Lumanu and the web crawling that provides all of our data.
ClojureScript powers our user interface. Using the same language on the backend (Clojure) and the frontend has been a big win for us.
Some of our machine learning algorithms are developed and implemented using Python. These algorithms help us recommend content and surface insights about content.
Elastic Beanstalk manages our environments. We rely on it to manage rolling out new versions of services.
PostgresSQL is our datastore of record. It is a flexible, poweful, relation datastore that fulfills so many needs.
ElasticSearch powers our free text search.
Docker Compose is one of the pieces that really allows us to get new developers up and running quickly.
As a remote company we rely on Slack for most of our communication. Ease of sharing links, creating private conversations, and developing bots makes it a solid communication tool.
Our interface is beautiful and serves up a lot of static content. CloudFront helps us deliver the content quickly.
We use this both indirectly through Elastic Beanstalk and directly for running some servers continuously. AWS is a solid provider of cloud services.
