DevOps: support for the infrastructure of current projects

Hi, we need server support for our projects.
Current task:
- setting up and maintaining a cuber in which ScyllaDB, PostgreSQL, Redis and Python/Go applications are used. The project is high-load (exchange trading).

Further tasks:
- Server support for projects both on the customers servers and on our own.

Requirements:
- Significant experience in setting up hardware for a project from scratch incl. standard technologies (virtual machines, containerization, CI/CD. monitoring installation, etc.)
- Substantial experience with cuber
- Experience with Scylla is desirable (or you can quickly figure out how to set it up)
