MUMPS is the infamous one that pretty much everyone is at least trained in, but Epic is 99.9% done replacing old VB6 clients with C#.NET + Typescript/React. There's also developers working with iOS and Android development, and Python and SQL for data science and business intelligence.

Is MUMPS still being used in any significant capacity at the company?

[epicdev]

Yes. The core database is programmed with MUMPS. There are extensive libraries and tooling built around it to ease pain points.

It’s still the primary backend language. We moved away from VB, not MUMPS.
