I started as a lecturer of Microsoft Server computer courses at 1995. Same years later, I started as Microsoft consultant for designing and implementing for high availability Microsoft infrastructure for enterprise companies. Most of the time in last 10 years, I dedicate as a cyber-security consultant for Microsoft active directory vulnerability and cloud security.
