Hi there!
My name is MOSTAFA and I am a Red Hat Certified Engineer (RHCSA, RHCE & RHV-M), working more than ten years of professional in Linux Security, Cyber security, email servers, Mautic, PowerMTA, bulk email, SMTP servers and Mailwizz. I understand that you are looking for someone to help with the implementation and migration process of Zimbra 8.x while also ensuring high availability using Pacemaker, CoroSync and cloud API.
I believe I am the best fit for this project due to my extensive experience in Zimbra 8.x migration as well as awareness of its built-in high availability feature. Additionally, I have the knowledge required to ensure success of the project such as client satisfaction certification and guaranteed solution delivery.
If you would like more information or would like me to discuss further please don't hesitate to reach out!
Thanks
