I love creating frameworks from scratch. Going down to the details and fundamentals in every browser, database, application, API or operating system. Making small in size, highly optimized and fast running apps.
Have got plenty of interests ranging from computer languages and programming through music, geography and history to weird topics like genetics.
In my free time I combine a few of them in my hobby projects - programming, games and music creation.
