Experience
- WasHere - Share and Discover the Secret Marks Around You
Was Here is anonymous local sharing in a radius of 500 meters around you:
• See what neighbors and people around you are up to
• Share photos and videos or just text
• Put your graffiti art into the cloud
• Play scavenger hunt games
• Discover exciting new things

LoveThis is an iOS native application for managing and sharing recommendations with friends. I've implemented almost the entire application with the following technologies: iOS, UIKit, Foundation, Core Data, Core Animation, and RestKit.
- The Times of London for iPhone
This is a news reading native application for iPhone, in which I implemented news downloading and offline mode support. I participated in all new features requested from the client.
- Pet Park
Pet Park is an iPhone 2D game for managing a park of pets using Cocos2D. I implemented many parts of the game engine, game play logic, and server communication.
- Earthrise
Earthrise is a 3D MMORPG game written in C++. I participated in various features for the client. I worked on the game servers and some of the tools such as the Model Editor and the World Editor.
- SketchList 3Dhttp://sketchlist.com/
SketchList 3D is a 3D cabinet design software for both hobby and professional users. I participated in improving the core geometry engine and implementing different client features.
- 3M™ Margin Marking Software
This application was designed for ditching, die cutting, and model trimming of teeth and was integrated as part of the 3M™ True Definition Scanner. I implemented an algorithm for smoothing a 3D mesh while keeping the feature edges and an algorithm for finding feature edges on a 3D mesh.
- Vouchhttp://www.vouchsoftware.com
Vouch runs a series of simulations using the top Toy Industry Standard Tests and toy 3D model to verify that toy is safe for use. I implemented various tests and participated in Bullet Physics integration.
