Experience

Hand Gesture Recognition

The computer takes videos of people performing hand gestures. The computer analyzes the input data and guesses what gesture the person executes. The algorithm analyzes ten different hand gestures.
I implemented a custom feature extraction algorithm and used OpenCV and SVM for this project.

EventListener

A website that offers information to users about their favorite bands' recent events. The user can listen to any music of any band on the website, watch their clips or subscribe to events. The project was written in Java using the MVC pattern.

PintOS File System

I created a file system for the PintOS operating system. I supported sparse and extensible files so that files could have any size. I wrote the code for caching data from disk to RAM so file system syscalls communicate with the cache, and the cache communicates with the hard disk. Cache has "read ahead" and "write behind" features, causing lower file access latencies.
