/Hobbies & Interests/
Coding
I love coding. I love thinking even more. That's why I code, because it makes me think. I dedicate most of my free time to do personal projects or simply solve programming challenges online to keep the ball rolling.
Reading
Apart from reading academic texts on Computer/Data Science, I love reading blogs and news articles on science & technology, business, economics, finance, politics and environment.
Blogging
Writing helps me organize and articulate my thoughts, and forces to teach myself new stuff—from writing opinion and commentary on my personal blog to posting my experiments on data on my data science blog.
Economics & Finance
Being the child of two bankers and having worked on building Trading Systems, I have a natural affinity for Finance. Plus, I love spending time understanding Economics: how markets and economies abide by the laws of supply and demand.
Cooking
I cook, not just to eat and survive, but for the sheer love of it. To me, there is nothing more satisfying than being able to turn some ingredients sitting idle in the rack into delicious food—and I'm very imaginative about it!
Design
Learning to design 2-D raster and vector graphics is my relatively new hobby. I am honing my Illustrator and Photoshop skills to bring out the best of the creative side of me.
Photography
I've had a long admiration for Photography and in recent years I have actually put efforts to hone my photography skills. Now I can call myself a wise amateur photographer.
