game overlay built

I am looking for an experienced and talented developer to create an in-game overlay for a role-playing game. The overlay should be designed with a map as the main element, allowing renderings of dungeons, characters and creatures on-screen as the gameplay progresses. It should also have support for features such as health bars and inventory. The overlay must be optimized for performance and be able to adjust on different devices and screen sizes so that the experience is consistent and immersive. The developer should have extensive knowledge and experience in game development, UI/UX design, and working with compilers and frontend libraries.
