I am a full-stack developer. I love programming,  design and know my way around server architecture as well.  I would never feel complete, with one of these missing. I have a broad range of interests, that’s why I constantly dive into new technologies and expand my knowledge where ever required. Technologies are evolving fast and I enjoy using the latest. Apart from that, I am a peace loving guy who tries to have people around him that think the same.  I truly believe in the principle: “If you help someone, someone will help you, when you need it."
