About

I’m an engineer, dreamer, hacker, data scientist and technophile who enjoys performing in-depth research and analysis, as well as developing end-to-end solutions that drive Business Intelligence and Growth.

Along with a strong background in analytics and a wide domain exposure, I possess a keen eye to comprehend the big picture with a penchant towards implementing workflow automation. I’ve worked in R&D, helped sales engineering and have implemented ERP systems (among other things).

I’m frequently available on IRC with the nickname shrysr on a bunch of channels, especially #emacs. I’m active on Linked in and Github, and occassionally on Twitter.
