Mayur Ramgir has more than 16 years of experience in the software industry, working at various levels. He is a Sun certified Java programmer and Oracle certified SQL database expert. He completed an MS in computational science and engineering at Georgia Tech, USA (rank 7th in the world for computer science), and an M.Sc. in multimedia application and virtual environments at University of Sussex, UK. He has also attended various universities for other degrees and courses, such as MIT for applied software security, and University of Oxford for system and software security. He is the CEO of a software company, Zonopact, Inc. headquartered in Boston, USA, which specializes in bringing innovative applications based on AI, robotics, big data, and more. He has single-handedly developed Zonopact's flagship product, Clintra (B2B-integrated AI-assisted business management software). He is also the inventor of two patent pending technologies, ZPOD (an automated cloud-based medical kiosk system) and ZPIC (an AI-enabled robotic in-car camera system) Nick Samoylov is graduated as an engineer-physicist from Moscow Institute of Physics and Technologies and has even worked as a theoretical physicist. He has learned programming as a tool for testing his mathematical models using FORTRAN and C++. After the demise of the USSR, Nick created and successfully ran a software company, but was forced to close it under the pressure of governmental and criminal rackets. Nick adopted Java in 1997 and used it for his work as a software developer-contractor for a variety of companies, including BEA Systems, Warner Telecom, and Boeing. Nick's current projects are related to machine learning and developing a highly scalable system of microservices using non-blocking reactive technologies, including Vert.x, RxJava, and RESTful web services on Linux deployed in a cloud.
