Solar LoRa Mesh Sensor Nodes

I'm building a fleet of autonomous, solar-powered IoT nodes that track air temperature, humidity, and soil moisture, then relay the readings through a self-organising LoRa mesh to a single internet-connected gateway. Each node is built around a Heltec V3 (ESP32-S3 + SX1262) mounted on a custom two-layer PCB that already handles solar charging, switched sensor power, a physical ON/OFF switch, and an external-chip-free autoreset tied to the ESP32 watchdog.
What I need is a PCB designer who can take a complete, documented design brief through to fabrication-ready files for PCBWay PCBA turn-key. Firmware and assembly are handled on my end.
Deliverables
Schematic (PDF + source file)
PCB layout
Gerber files + drill file ready to upload to PCBWay
BOM with LCSC part numbers for PCBA turn-key
Pick & Place (CPL) file
About the brief
A full design brief is provided: complete netlist, BOM with LCSC part numbers, layout constraints, mounting hole positions, and both official Heltec V3 datasheets. If your experience tells you something in the design is wrong or could be improved, flag it and we'll review it together before finalising. I'd rather catch a mistake now than after fabrication.
Hands-on experience with 2-layer SMD PCB design, buck converter layouts, and PCBWay/LCSC workflows is essential.
