Multi-Tenant ERPGO SaaS Modification -- 2

I need my existing ERPGO SaaS system modified to support multitenancy. This includes:

- User authentication adjustments
- Changing the database structure to support separate databases
- Setting up subdomain routing for each tenant

Currently, we are using MySQL.

Note: The code of multitinancy and creating a new database for every tenant is ready, and the database structure. I just need to implement the files in erpgo saas system, and sure to be fully working

Additionally, I require an automated database provisioning system for new tenants.

Ideal skills and experience:
- Expertise in MySQL
- Experience with SaaS multitenancy implementation
- Knowledge of user authentication systems
- Proficiency in subdomain routing
- Automation skills for database provisioning
