Have installed more than 10 ECC IDES on Oracle, Sybase and MSSQL, I have installed S/4HANA 1610 IDES version in 1 day on AWS r4.8xlarge for around 6-7 times. I've been working on SAP from 8 years, and now I am working in a golden partner in the middle east as a BASIS team leader.
I've done dozens of installations of SAP systems as I have an SAP and Siemens employee in the past.
Currently I am a Senior Consultant in a consulting agency.
