Electronic product design and IoT

I am looking for a freelancer to help me with a product development project. The project requires the design of an electronic product that integrates with the Internet of Things. As it stands, the product will be a hardware product, although we may explore options for hybrid solutions in the future. Specifically, I need assistance with prototype development, specifically in the areas of design consultation and production resources. Additionally, I have some existing requirements that need to be taken into account when designing and developing the product. I am looking for an experienced freelancer who can create a product that meets all of these requirements,the ideal candidate will have a strong understanding of both hardware and software development processes and possess experience in designing and developing various types of electronic devices.
