"

Beyond the code, I enjoy doing the simplest things in life with my family and friends.

When I'm not glued to my screen, you can find me raising 10 times the big blind preflop in Poker, finding fresh powder and untouched lines in the mountains, or catching squids under the moonlight in Seacrest Park.

Life is a series of experiments, and I'm just here collecting the data.

Cherish the gift of life by living in the present.
