Java SDK developer needed

Hello developer,

I have a biometric attendance device -Chinese brand-Timmy. This device can sent attendance data to cloud server using p2s aka push to server method. This process works through a SDK made on java. I have the source code of the java SDK with some instruction. I need a developer to check the code and built a SDK for me.
If anyone have experience on this and interested to do the task , please dm me.

Here is the google drive link for the SDK source code--- https://drive.google.com/file/d/1Uxqmnko9RzYISLgwHR_3XMkdjrEdoSkh/view?usp=sharing
