Websocket connection with STM32 and Wiznet W5500 -- 2

I'm seeking a well-experienced developer who understands STM32 and IoT. This job focuses primarily on Ethernet connectivity to achieve optimal functionality.

While not necessary I will favor developers who have the hardware at hand and can test themselves before finalizing the project. Any prior experience in Embedded development, File transfer, Network communication would be an added bonus.

Key objectives are as follows:
- Establish Websocket connection to public domain
- With Wiznet W5500 and STM32 microcontroller.

The ideal candidate should have:
- Proficiency in Wiznet development
- Proficiency in STM32 development
- Extensive experience with Ethernet connectivity
- Understanding of data transfer speeds and protocols.
- STM32 and W5500 modules at hand

Your job will be to write an optimal code, preferably in STM32CUBEIDE or Keil MDK Arm. The Wiznet W5500 is connected to STM32 via SPI, it should connect to ethernet router with DHCP mode and afterwards establish and maintain a websocket connection to public domain, sending and receiving data. The code should be clear, well commented and easily readable-reusable.
The devices used are STM32F103C8 and Wiznet W5500.

Please, make your bid indicating your understanding of the project, and your proposed timeline for completion. Thank you.
