Course Information

Krish's Profile

Krish is a Microsoft Certified DBA with 9 years hands on experience in SQL Server Administration, SQL Programming, and Performance Tuning. In database administration, Krish have been contributed his skills in Administrations, High availability setup, monitoring, performance tuning with application and users’ queries, optimization of queries for faster performance. He is working with multiple clients for re-architecture of SQL servers, set up of high availability that includes Mirroring, replication, log shipping, clustering and always on. Currently working on new architecture of SQL server, work on existing configurations and settings to review current configuration for better performance. He is also well experienced in system level performance tuning using third party tools like Redgate, Idera, SQLDiag and in-built tools like Performance monitor, task manager, resource manager, SQL Profiler, query tuning advisor, activity monitor.

Live Training Videos

We believe in letting our prospective students to watch recorded videos of our live training classes and decide for themselves. If you would still like to attend a one-on-one live demo session, please give call Daniel @ 267 718 1533 and he can schedule one for you at your convenience.
