At edenceHealth, we deliver Dockerized Python programs and infrastructure-related code. We also work in Java, Javascript, and R. Our development environment is Mac-based, but we typically deploy to Linux-based VMs and cloud services.
On routine projects, we work with one or more of the many different relational databases that our customers use (e.g., SQL Server, MySQL, Oracle), but Postgres is our database technology of choice. We manage our code on GitHub and often deploy projects and data to AWS.
