You can find several open-source projects that were developed by me in my GitHub account.

Adding OASIS Format Support to the IC Station and Schematic Editor

While working for Mentor Graphics, I was involved in adding OASIS file support to several EDA tools including the IC Station and Schematic Editor. OASIS is a more compact version of the industry standard GDSII format.

YouTube Monetization

While working for Google, I was involved in building and improving the video monetization and claiming features of YouTube.

AI Based Poker-Playing Software

While working for a freelance client, I led a team of four in building an AI poker-playing engine. The whole project was built from scratch using C++, including card clustering, hand strength, the Nash equilibrium training algorithm, and opponent modeling. At the end of the project, the system was able to play champion-level Texas hold'em poker.

White-Box Encryption Based on SAFER+

I led a scientific team of cryptographers in building a white-box implementation of a SAFER+ encryption algorithm. Extensive research was done and a C++ implementation was provided. The novel cryptosystem was then sold to Samsung to be patented.

Musical Notes Application

While working for a freelance client, I worked as part of the team which was building a musical notes application. The app was able to run on a web page, desktop computer, and mobile—providing the ability to the users to get musical notes for popular songs, then edit and mix them.
