Hi there!

I have been working in IT industry for more than 10 years and still trying to learn new things and always amaze to see the changes coming in the industry.

Though I've been involved into various fields such as AIX, POWERHA, LPAR VIO, LINUX, LINUX CLUSTERS, VMWARE VIRTUALIZATION AND OPENSTACK, DevOps, etc. I still find myself as the aspirant to this technology and learn new things every often in the field or in the classroom.

As a trainer it is always a challenge to give best of your ability and satisfy the students from different background and expectations,

By God's Grace, I've been teaching the above said technologies for the same duration,with over 300 batches including online/offline , corporate etc. and happy to know my students find me satisfactorily doing my job as per their expectation and making the subject simple and understandable.
