NFC reader Schematic and PCB design.

I am looking for a freelancer who can design a simple NFC reader, which consist of an NFC antenna (on FR4 1.6mm PCB) which must fit into a predefined space of approx. 30mm x 60mm and a separate PCB with the NFC controller and the supporting components. We will provide PCB outline and critical component placement in an Altium file. This will be a commercial product and must meet CE regulations.

Particular to this project is that it will have an RGBW led in the middle of the antenna, which may impact the antenna calculation and performance. The LED traces are going to the edge of the antenna and are connected to an MCU, so this LED itself is not part of the project (but will be physically present on the antenna PCB). Tags should be readable over a distance of at least 5cm.

I expect that you have experience with NFC design, that you can draft a schematic and provide a PCB design in Altium within days to a week. There aren't much more requirement than those mentioned.

In addition, I would need a basic API that can run on STM32G030K8T6.
When an off the shelf purchased tag is placed in front of the reader, your provided API will fetch the tag ID over I2C and just save it in a register, noting much more.

Please place your bid for schematic, BOM and pcb design ONLY.
If you can write the simple API, then please quote the EXTRA cost for this as well in your message (but do not include it in your bid price for now).
If you can test the PCB as well, then please quote the EXTRA cost for this as well in your message (but do not include it in your bid price for now).
Thanks and looking forward to your proposal!
