I would need experienced PCB designer for my project.
Project based on ESP8266 with few I2C sensors, relay, needs to be modular, small factor very similar to SONOFF build.
There will be two versions of device 220V and US 110V. All design must comply with European, and American electrical industry regulations.
Would need Gerber files and diagrams.
Whole project will be release open source for community of Domoticz, OpenHub and Homeassistant.
Ideally I need someone with ESP8266 experience.
