Not only your content has improved, but the way you tempo the sequence – content and humour is very effective. He has been appreciated by the student community for an excellent session and extended help that goes beyond workshop events. He is actively keeping update with technologies and has incorporated latest developments in his workshop. Your ability to choose the difficult and challenging topic like Big data and Hadoop and coming out with an impressive presentation indicates that u have a great potential untapped yet. I cherish his association and wish many years of collaboration in future.
