About Shkelqim

With 3-4 years of practical IT experience, I support companies in making their IT infrastructure secure, structured, and future-proof. My focus is on IT security, identity & access management, and the administration of Windows server environments – complemented by practical experience in web development for internal solutions and company websites.
I take on projects with a clear scope and deliver results that last long-term: from setting up and hardening Windows servers to implementing IAM concepts with Active Directory and Microsoft Entra ID, to realizing internal web projects.
My core services:

IT Security & Identity Management (AD, Microsoft Entra ID, Group Policies, authorization concepts)
Windows Server Administration & Hardening
Web Development for Intranets and internal company tools

I work precisely, document carefully, and communicate transparently – remotely or on-site in Berlin and its surroundings (service radius 50 km).

    September 2021 - Today (4 years and 11 months)
    Berlin, Germany
    Since 09.2021, I have been responsible for the administration and further development of the Windows Server and Active Directory infrastructure at Deutsche Rentenversicherung Bund – one of Germany's largest authorities with correspondingly complex IT requirements.
    My main focus is on Active Directory, Active Directory Federation Services (AD FS), and Azure AD Connect (AADC): from daily administration and maintaining trust relationships and federation configurations to synchronizing identities between the local AD environment and Microsoft Entra ID. In case of synchronization errors, I independently analyze the causes and resolve them sustainably.
    Focus areas:

    Active Directory Administration & Development
    Active Directory Federation Services (AD FS) – Configuration & Operation
    Azure AD Connect (AADC) – Setup, Operation & Troubleshooting of Synchronization Errors
    GPO Management & Group Policy Planning
    User Management & Authorization Concepts
    System Stability & IT Security in the Enterprise Environment
    Identity and Access Management Windows Server
