Experienced Android Developer with 4 years in the industry. My first contact with a computer was when it counts as a reward to play with a computer as a child. A couple years later I owned my computer and after 5 month I could fix my relatives computers. That was when I realized that I have a lot to do with computers in my life. I chose Software Engineering as my university field and started working as a freelance developer since then. I started many projects by myself even during my college, which has continued after I started working as an employee. Now I want to scale my skills and work with international companies to become the best in what I love.
