"I hired Martin to help me with coding work for an Android project. He now works for me for over 3 months and we still work together. What I love about Martin is how flexible and reliable he is. Even on weekends I always got an answer to questions or problems that needed to be solved. He's my first address for any other Android work I'll have in future and I really recommend you to consider him, too."
