Hi I’m RJ and I’m a hooper, gym goer, swing trader, and software engineer.

I completed B.Sc. at Carnegie Mellon’s School of Computer Science, with a concentration in computer systems. I also had a double major in applied mathematics where I focused on computational finance. My academic interests are databases and computer systems optimization.

I like sports, traveling, films and music.

Less FOMO, lighter EMO, better YOLO.
