Working on ESP8266 Arduino Style board


I am working on a project for quite a long time but couldn’t complete it. I want to create an Arduino UNO style board of ESP8266. We were using Arduino YUN before and now we want to replace it with ESP8266, may be ESP32 but we need to place different shields. Someone shared this link with me in this forum: ESP8266 Arduino UNO - Share Project - PCBWay but no help. I am trying to design exactly same shield but couldn’t find the design anywhere. IF someone could design it for me or give me some help, really appreciated.
