    I support companies in making their IT more efficient, secure, and future-proof. My focus is on implementing projects in the areas of cloud, IT security, managed services, and process automation – from conception to the finished solution.

    Thanks to my experience in projects with small, medium, and large companies, I am familiar with the typical challenges: inefficient processes, lack of integration between systems, or increasing demands on security and compliance. This is where I step in and develop solutions that are technically reliable, user-friendly, and sustainable.

    My expertise includes, among others:

    Managed Services (Workplace, Backup, Web Hosting, Endpoint Security)

    Cloud Solutions & Microsoft 365 (Setup, Integration, Automation, Data Backup)

    IT Security (Mail Archiving according to GDPR/GoBD, Firewall, Virus Protection, Failure Protection)

    Network & Infrastructure (Cloud Telephone Systems, Monitoring, Proactive Maintenance)

    Individual Workflows & Process Optimization (Automations, Integration of Existing Systems)

    Why work with me?

    Practice-oriented solutions that really work in everyday life

    Flexible – from short-term projects to more complex IT rollouts

    Clear communication, transparent working methods, and reliable implementation

    I see myself as an equal partner who not only delivers technology but also creates real added value. Whether it's security, cloud, automation, or network management – I help you implement the right solutions and sustainably strengthen your IT.
