Apart from being a Manual Quality Assurance Engineer and Project Manager, I enjoy photography. I have an analog camera (film) and a digital camera, which I always take when traveling.

In my free time, I like to watch movies or read new articles about testing. Also, I like to attend music events dedicated to heavy music.
