Hi! I'm Sean.

I'm a software engineer and indepedent iPhone app developer

About Me

I've studied at UC Berkeley and Vrije Universiteit Brussel. Recently, I've also worked as a software engineering manager at Ancestry.com. When I'm not coding, I like to travel, scuba dive, and play chess.

Here are some of my side projects

SeaReal -  An iPhone app that color corrects underwater photos & videos (e.g. for adding color back into footage taken during scuba dives).

OR

DEEP BLUE AND GOLD (Link) - Built with two other students for my EE149 (Embedded Systems) final project at UC Berkeley. Constructed a plexiglass chess board that provides hints and legal moves for a human player while he/she plays a computer. The hints, legal moves, and computer moves are indicated by Neopixel LED strips underneath the board. Piece positions are detected using magnetic reed switches underneath the board and magnets in the pieces. I programmed the chess AI system for the board, and helped wire the circuitry.

ROCK 'EM SOCK 'EM - Modeled with a project partner for a student-led 3D Printing and Modeling course at UC Berkeley. All parts were modeled using Autodesk Fusion 360. The .f3d file can be downloaded here.

Below is an expanded resume. A pdf can be found here.
