At RN-Inform | Sibintek, I supported enterprise Microsoft infrastructure with 170,000+ users, 180,000+ endpoints and 12,000+ servers, focusing on availability, security and operational reliability.
I participated in Active Directory migration and domain consolidation projects, working with environments of up to five domains and five forests. I supported migration planning, implementation and post-migration stabilization, including trusts, SIDHistory and Group Policy migration.
I developed PowerShell scripts for infrastructure administration and security operations, including Domain Controller event auditing and Windows Firewall event collection. I also automated Group Policy deployment and verification tasks.
I administered and supported SCCM/MECM, Windows Server, WSUS and Hyper-V, and worked with SQL Server and Check Point firewall environments. My training includes Microsoft certifications and Check Point CCSA and CCSE certifications.
