    Angular on Rails developer (Full-stack)

    Poland - Last active: 25 days ago

    Who am I? I am a full-stack web developer with strong design and marketing background. I love all kinds of challenges which give me an opportunity to make myself bigger. Studying for 7 years in USA made me believe that everything is possible. I am not just another robot-like developer who will do everything you say. I am not afraid to disagree with your opinion, and say that something can be done better. Before asking "How?", I tend to ask "Why?". There is always something that can be improved. Why am I here? I am here to work on exciting projects and meet interesting people. Also, and it shouldn't come as a surprise, I am here to make some money. I need to pay my bills so that I can focus on higher goals. What makes me tick? My personal motto is "Be ashamed to die until you have won some victory for humanity". What does it mean? It means that I love to work on projects, which make the world a better place. What else do you get by hiring me? In short, if your business does not have a purpose, let me find it for you. People say that I am really good at it. I have to admit that this is the only thing that brings me more joy than programming. Since this is my "hobby", you will get this service for FREE.
