Kumaran P

I'm an avid developer who encourages **Learn and share** methodology. I always believe that _sharable knowledge is worth_. I've _visited various colleges and university to train students for their placements and higher studies_. The timer won't start until I understand the issue/request completely and if I cant fix the issue will refund the money completely.
