Hi, I am looking for PCB designer to design a PCB and plastic enclosure for my prototype. this device connects to LED strip and controls the LED color and animation. I used ESP8266 / ESP32 but I am open to any other suggestions. The mobile app and the code is ready and I just want the controller to be ready for commercial. The attached image is similar to what I am looking for Thank you
