During his years at the University of Sofia studying theoretical physics, Nick was involved in multiple on-campus activities including an early research in neural network simulations in the context of complex problem solving, numerical methods and simulations of dynamic systems. His passion for programming led him to further his studies in Information technologies at New Bulgarian University. To support himself while studying, he started developing games and interactive apps for the web early on. Due to the high demand for interactive experiences his practice rapidly expanded in to a successful software development and consultancy business catering blue chip clientele of the Fortune 500s since 2003.
