Develop custom board

Hello community

I hope I find you well and safe

I am starting out in the arena of Jira development and trying various examples and tutorials to learn and improve.

One aspect I would like to try out is to create a custom board plugin. Similar to a scrum or Kanban but with configurable row and columns where “cards” (not and issue at that time) are placed then via a set of buttons and configs a set of Jira issues are created.

I am not looking for a commercial product nor am I trying to develop a commercial product.

I have googled but the results are always around developed Commercial plugins on the marketplace rather an example or tutorial.

Is anyone aware of an example or tutorial or at the least where I should start looking in terms of a keyword for a search that doesn’t end up with a marketplace item?

Super thanks in advance
