I need a digital console development team or an experienced system engineer

I am looking for a development team to create a digital mixer for live performance. The platform should be available on both iOS and Android. While I don't have specific features in mind, I do have some general requirements that I would like to discuss with the development team. The ideal team should have experience developing digital consoles and be able to come up with features that would enhance the live performance experience. Or maybe you are a senior audio engineer and we can talk.
