Dave Nickens, Director of Mobile at Build.com

Karthik worked for ebay Mobile Platform in the Tracking and Reporting team during the summer of 2014. In a very short time he was able to gather stakeholder requirements, align on a direction, and deliver a working prototype of the eBay Mobile Executive Summary Dashboard using Mobile Analytics Certified Data. Karthik is a driving force once he is given a task. Just empower him and get out of the way!

Vinay Prabhakaran, Senior Technical Project Manager at Snapdeal

You will find Karthik as an awesome, fun to work with and really intelligent person. His problem solving skills and creative thought process helped our team win great success. His passion for data and analytics could be easily seen in the Leadership Monthly Dashboard that he created. He had real mastery in his work domain and won a lot of respect from his peers.
Though he gives you a very no non-sense serious person first impression, he will grow on you as a fun filled humorous guy.

Surya Narayana Murthy, Senior Consultant at CoreCompete Ltd.,

Karthik & I innovated Infoboard as part of the Next Big Idea, an innovation contest of Target Corporation. He is very creative and a true out of the box thinker. Not just that, once he sets his task, he really goes after it and finishes it.

I found that he always thinks from the customer's perspective. When we were challenged, his problem solving skills and a customer centric perspective allowed us to brainstorm fitting solutions. One of them, that we finally implemented is Infoboard that really solved a lot of existing business challenges.

All the best Karthik,

Surya

Vyasaraja Ramamoorthy, Project Manager at Cisco Systems

Karthik joined in my team right after his college. His interest and motivation towards learning new products and technology allowed him to scale up very quickly.

He is a keen listener, asks question when required and works hard till he gets hands-on with the product.

I have to bring out his patience when it comes to dealing with people. His counterpart was a tough guy to deal with, but Karthik handled him with ease,

I felt, overall, he was a good find for our team. He is a man with potential and skills.

All the best!
