Hello, Dominik
As a seasoned game and mobile app engineer with over a decade of experience, I am confident that I can deliver the immersive, high-performance mixed-reality experience you envision for your project. My 10+ years of expertise with Unity3D and proficiency with Unreal Engine are perfectly aligned with your requirements for developing on Apple Vision Pro.
My experience isn't just limited to mobile app development but also spans VR/AR development, an essential aspect when working with mixed reality applications. Notably, I've led successful development projects with massive user bases, similar to your company's future goals. Efficiency has always been my priority, as exemplified by the 40% improvement I made in frame rates on a VR project through optimized rendering.
By choosing me for this project, you're not just hiring a freelancer but gaining a partner who can ideate along the way and contribute beyond code. Ensuring complete ownership of our work as per your request, I'll provide you with the full code and all relevant files to enable easy modifications in the future. And as we share an interest in Reality Composer Pro for development (though Unity is also fine), it is clear that we have already aligned our methodology. Let's discuss further and hit the ground running!
Sincerely
