ESP32 Based WiFi Temperature Sensor -- 2

I am seeking a freelancer with expertise in ESP32 based WiFi temperature sensors to develop a battery-operated sensor with a wide temperature range. The ideal candidate should have experience in designing and programming these sensors and be able to deliver a functional prototype that can measure temperatures accurately. There are no additional sensor features or integration with other devices required for this project.
The developer will
1. Make schematic + BOM
2. Make PCB files
3. Test, debug final units and ship fully functional units.
