Neptune.ml is aiming to become the collaboration standard for data scientists (like GitHub/GitLab are for software engineers).
Some of the things we do are fairly run-of-the-mill engineering work (REST, SQL, NoSQL), but often we do something quite rare! How many companies have implemented a fully featured GoogleDocs-like real-time collaborative editor? Or a custom autoscaler for an in-cloud Kubernetes cluster?
Java is our weapon of choice, but – keeping our stack as elegant as possible – we always choose the best tool for a job: parts of our system are written in Scala, TypeScript and Python.
