Experience
Facebook Toolkits
Created a toolkit that simplifies and speeds up development of Facebook applications. The stable interface reduces maintenance efforts affected by frequent changes in the Facebook API. It received excellent feedback by numerous developers and companies, including Epic Games Inc.
Chess Engine
I created my own artificial intelligence algorithm that was strong enough to win against most casual players (tested by my friends and myself).
Operating System
Startup code written in the boot sector that is used for starting an OS. The file table is used to store information about file positions on the disk. It includes functions for storing files on a disk, deleting, and renaming. Executable files can be executed from a command prompt. It includes support for resident programs.
Digital Circuits Simulator
This features two separate programs written in the C++ programming language, editor, and simulator. It supports basic logic gates, buses, special gates (one-way, two-way) and modules. It features acceleration of event-driven simulation based on usage of modules. It is tested on circuits of all complexities (from bistabil to simple microprocessor), and was suggested for a rectorial award.
