I've been involved with iOS, Android, RubyOnRails, BB and PhoneGap development at some point of time or the other.

Some of the apps I've made in my spare time:

Tides (A Board game you won't get bored of)

Tap Up: Android, iOS

doob

Flying Janken (Inspired by flappy bird)

AirBook (Links to paid iOS, free iOS and free Android apps)

'Ask Rahul'(Gandhi) (Android only)
