Experience
Aureum
https://github.com/matisseverduyn/aureum/Perfect formatting and readable text that adapts automatically to every screen size. Aureum uses the golden ratio to simplify responsive web design, which keeps class definition requirements to a minimum, making HTML and stylesheets cleaner and more manageable.
Permamarks
Save a complete copy of any webpage. Permamarks was a web archiving tool that enabled users to create a full, working archive of their bookmarks while preserving the integrity of the CSS rules and certain JavaScript functionality.
Scramblage
Send password-protected photos to anyone. Scramblage uses a proprietary algorithm to encrypt images, keeping them shareable as PNGs of the same dimensions but not viewable unless you know the password to decrypt.
StatFreak
An MLB pitch sequence research and prediction tool. Using pitch data, the PITCHf/x database, StatFreak could predict the next pitch type and location during a live at-bat, given the history of the pitcher and their relationship to the batter and other similar batters.
Backyard Bandits
A game where a gang of squirrel backyard bandits are after the player's dog bones. Players can move the dog around the screen to catch the pesky critters in the act, collect acorns to purchase upgrades and unlock new characters, grab power-ups for an in-game boost, and avoid getting sprayed by a skunk.
Pixits
A game where Pixit-making machines push Pixits from pumps at the top of the assembly lines and collect them in bins at the bottom. The problem is the machines aren't as reliable as they used to be, and sometimes, Pixits don't match the color of their bin, so players need to sort out the duds.
SQ Game
The player has a set of lights, but they're turned off. One by one, the player tries to turn them on, only to realize there's more to it than a few easy clicks—the wires have been crossed. The player must find and remember the connections to complete the round in the fewest moves possible.
