Hello,
I've worked on all aspects of LoRaWAN systems, from designing low power end nodes, all the way to gateways and the network server.
If you have a look at my profile, you can see my work on designing a LoRa powered smart water meter and custom LoRaWAN gateway. This is in addition to over a decade of experience in general electronics design.
Feel free to get in touch if you would like to discuss your project further.
