Product Design with PCB Expert

I'm seeking assistance in designing a product that incorporates a PCB. While the specific functionality and form factor details are flexible, the focus is on creating a working design that meets foundational needs. Expertise in PCB design, along with a solid understanding of incorporating features like wireless communication, power management, or sensors, would be beneficial. The final deliverable should include a functional design ready for production or prototyping, with close consultation on requirements throughout the process.
