Who Am I ?


I am a software engineer based in the San Francisco Bay Area, specializing in web and mobile app design and development, testing and release automation, and aviation systems analysis.

I graduated from Cornell University in 2010 where I obtained both my Bachelor's and Master's degrees in Mechanical Engineering with a focus in Aerospace Engineering and a minor in Applied Economics and Management.

I have a passion for anything technology, airplane, and music related. In particular, I am currently working on mobile apps (both design and development) and pursuing a private pilot license in my spare time. I've also been playing the drums for about 8 years and am teaching myself piano and guitar. I also dabble in the stock market, through which I am quickly learning the virtues of patience.


There are several principles that I live by. Learn a new skill every single day. Become the best that you can possibly be without sacrificing the important things in life (family, significant other, friends). Work hard, play hard, then sleep hard. Stimulate the mind and energize the body as often as possible - one cannot live without the other. When the body is weak, the mind follows. When the mind is weak, well..."a weak mind is like a microscope - it magnifies trifling things, but cannot receive great ones."

  • Image Checkmeister
    Incepted February 2012

    Checkmeister is the fastest and most comprehensive way to split your table's check. Split shared dishes, add coupons and deals, and email your results out to everyone. No other app comes close to the features packed into Checkmeister.

    Checkmeister is all you need when dining out with friends (besides your wallet). It is a powerful and versatile tool that combines the best of all tip calculators and check splitters out in the app market. Need to split the check in a hurry? The Even Split mode allows you to calculate tip and split evenly between any number of people on the fly, combining speed and convenience. Want to make sure that everything is fair and square? Not to worry, the Itemized Split mode allows you to specify who ordered what, which items are split among who, and apply coupons and deals to calculate the totals for each member. Save yourself, your friends, and your waiters/waitresses the hassle and frustration of trying to calculate everything for everyone at the table.


  • Image Secret Santa!
    Incepted November 2011

    Get ready for the holidays! This app provides the simplest way to start a Secret Santa (or Kris Kringle, or Monito Monita - they are all the same thing if you didn't know already) among friends, family, and coworkers.

    So easy to use, even your new 4 month old family member can join the fun! Is there someone, or multiple people (gasp!), in a Secret Santa group that you don't want to give gifts to? No need to worry, you can select as many people to add to your "Do Not Pick" list. Also, no need to re-pick because you picked yourself, the app will take care of it. Got paired up with someone in the group last year? The app will remember who you picked, so next year you don't get the same person again. Is someone not physically present when drawing names? Why not email or SMS to him or her using this app?

    So gather around all your friends, family members, and coworkers and make the holiday, party, or event a memorable one for everyone.
