Database Server Setup with RAID Configuration

I need an expert to set up a new server for me. This server will be primarily used for database storage. The specifications are:
- 2x1.7TB NVMe-SSD in RAID 1 for the Ubuntu OS
- RAID 5 with 6x-7.8TB NVMe-SSD

The database I plan to use is MySQL/MariaDB. Please note, I need Nginx pre-installed on the server as well.

Skills and experience required:
- Extensive knowledge on server setup and management
- Proficiency in Ubuntu OS
- Experience with RAID configurations
- Proficient in MySQL/MariaDB
- Familiarity with Nginx
