abtis Modern Teamwork Roadshow 2019 – Die passenden Anwendungen für reibungslose Teamarbeit – Wandel in der Arbeitswelt


I work as a Solution Architect @abtis. My goal is to enable companies and their users for a modern workplace based on the Microsoft 365, Teams and (still) Skype for Business (Server) to be more productive.

From 2011 onward, till today, I’ve been working in several areas in IT but found my passion in the communication and collaboration space with Microsoft Teams and related tech.

My daily business are projects around Microsoft Office 365, Exchange, Teams, Audiocodes, SIP Trunking, All-IP.
Typical tasks as a Solution Architect are customer workshops, planning of complex IT projects, developing concepts, managing projects, implementing and migrating to target solutions and services, troubleshooting (2nd level support) and service operation optimization.

Due to the fact that I’m always learning (the lastest and greatest tech stuff) and want to have my skills certified. I am Microsoft Certified Teamwork Administrator, Microsoft Certified Azure Administrator, Microsoft Certified Solutions Expert (MCSE) Productivity, Barracuda Essentials for Office 365 Certified Product Specialist and TOGAF 9 Certified. Plus many other certifications. For more details, please see my social media profiles certification details.
