I am a Software architect, developer, programmer with over 10 years of experience in Unity3D and .NET technologies. In the past few years, I grouped with other talented developers and graphical artists and created our startup company to solely focus on creating games and interesting applications in Unity for mobile, desktop, and VR/AR platforms. To fund our own games development, we help/work with other enthusiastic people here on Upwork. We can help you design, create prototypes, proof of concepts, for both single and multiplayer games efficiently in Unity to any platform. We love brainstorming, planning, designing, and create the best together with whom we are working with and we treat every project we are working on as if it was our own. We are the type of people who tries to always aim for the best work and we tend to give ideas, opinions where we think it can improve the project we work on. We also regularly report on our progression as client satisfaction and quality work are very important to us.
