Sergey Olontsev

I have been working with databases for about 18 years, started with SQL Server 2000. Nowadays, my experience is much broader to various other technologies, both relational and NoSQL databases, different programming languages, etc. I'm focusing on high availability and disaster recovery solutions, ETL, troubleshooting and performance tuning, developing data intensive services and products, processing terabytes of data each day. I’m a regular speaker at SQL Server user group meetings, SQLSaturday events and other conferences. An owner of MCM certification and MVP award on SQL Server (2013-2019).
