Information Processing

I have been working with data, information and various databases through out my professional career. Making meaningful insights from the data has been my passion along with building data models to store and retrieve information efficiently and effectively. During this course of journey, I have built complex data integration systems and workflows to process terabytes of data.

Capture Memories

In last 18 years, I have been capturing memories in form of photos and videos. Over this period, I have clicked around 50000 photos and terabytes of videos. This itself is a high volume of data with immense information. All the images on my website are captured by me on various adventures and vacations. I have dwelled into landscape photography, macro photography and portraits as well. Click here to view my gallery!

Adventures & Recreational Activities

National Parks in US

United States of America has some of the most beautiful national parks. I have visited some of the prominent ones: Yellow Stone National Park, Yosemite National Park.  On my list are the Arches National Park, Glacier National Park, and few others.

Mahesh’s enthusiasm for teaching has truly been inspiring. As the TA for his ACO 102 class, I consistently hear excellent remarks about his teaching from his students. Every semester, Mahesh always improves the class by introducing new topics that helps engage the students. Just as he excels in his teaching, Mahesh is also very knowledgeable in his field. As his research assistant, I was able to learn graduate level topics since he always explains concepts in a way that makes it easier for me to understand. In fact, Mahesh has been the person that has influenced me to pursue a graduate degree. I am forever grateful that I was given the opportunity to work with such a unique and inspiring individual these past couple of years.
