I'm very passionate about data. I get kick from making information visulizations to explain trends in data. I love this because machine learning is better explained through appropriate visualizations. This would be the most exciting area for me where i can make potential contributions.
On systems side, I really love working on performance improvements and optimizations. I have a background in programming contests during my undergrad years.
I try my best to stick to best software practices when it comes to maintaining code bases but i'm not obsessed( read as i understand business side of technology).
