Working in a technology corporation, our creative hub realized the necessity of presenting these technologies at various major events, such as at the Mobile World Congress. Interactive demos were chosen as the best presentation platform. We handled the entire process of creating demos, from forming briefs in collaboration with engineers and developers, designing UI/UX interfaces, creating layouts, to full implementation using HTML5, CSS3, React JS, and Unity. During our work, 2 of our projects were recognized as the best demos in the NTN sphere. The development was carried out by a team of 3 to 4 people, where I managed client communication, brief formation, partial programming, oversight and review of designers’ and programmers’ work, and overall team coordination. We presented 6 interactive demos showcasing various technologies.
