I have already made contact with HamCQ and several other amateur radio groups, and I've always enjoyed software development. Therefore, I plan to develop my own QSL card system.
Currently, access is via the web interface. A desktop version is under development, and I am currently using it myself. It's estimated that sharing will be possible around early October. The mobile version is expected to be completed in late December.
The idea is to use HamCQ's QSL card exchange module (out of the 119 cards received, 104 are from HamCQ), allowing users to register receiving and sending cards, communication logs, and a personal center within the system. (SMS notifications have been implemented).
Currently, we have completed the development of computer versions for receiving and sending cards, data statistics, and SMS push notifications. The remaining functionality that we are still considering implementing includes:
If you don't have urgent matters, we can launch the first version for trial use by September 30th. We welcome your application to join (due to the recent start of the semester, processing and issuing of applications may be slow, please understand).

I tried something similar a while ago, but it didn't work out because of the college entrance exams; it ended up being a complete failure. If you have any ideas or suggestions, and you understand MySQL, I recommend that you join the development team.
