Blocks Slider Puzzle
Simulates and solves a block slider puzzle. Attempts to find a set of moves (each move slides a block N, S, E, or W), using a directed breadth first search, that can manipulate the puzzle from a given starting config to a target config.

Audio and Images
This is an audio and image association iOS app I developed at CodeBros. In this app, users are played an audio file and attempt to choose an image that corresponds to the audio from an image bank containing 4 choices. It intends to help users with special needs improve their ability to associate sound with images.

Piano Key Board
This is a 2-octave piano keyboard iOS app I developed at CodeBros. It features a free-play and tutorial mode, in which users learn the fingering of simple songs.

A Matching Game
This is an iOS app that I developed at CodeBros in which users attempt to match pairs of face down cards. The number of pairs on the table increase every round.

Tic Tac Toe
This is simple tic tac toe iOS app I developed at CodeBros. It features 1-player and 2-player modes.

Tron Light Bike Game
• Created networked multiplayer game in Java simulating Tron light bikes
• Involved in entire process including architecture design, APIs, user manual, test plan, and test program
