Hello. I am a freelance programmer, working for a variety of clients all over the world. I specialize in software development, and the projects I've done range from small one-day solutions of tricky tasks and programming consultations to many-months projects, from writing device drivers to database applications and website backend programming. I enjoy my work, and try to deliver most quality software possible within the selected budget.
