Senior🎓
Top SchoolJoachim Otahal is a seasoned Senior System Engineer based in the Stuttgart region with over three decades in IT and more than 10 years in senior roles, specializing in Windows Server and Exchange platforms from legacy releases through Server 2022 and Exchange 2019. He brings deep expertise in virtualization (VMware, Hyper-V), cluster upgrades, AD and Exchange migrations, network design, and hardening through auditing to prevent outages.
