Hi @ejri and welcome to the OpenEMR project!
We are definitely open to custom projects and looking forward to reading your recently posted custom project proposal.
If you have not done so already, ensure you check out this post for some details:
OpenEMR is participating in Google Summer of Code 2020!
Would also suggest participating on OpenEMR’s github repo and working on a simple mini-project (such as a simple bug fix or simple feature) to interact with the OpenEMR developers and learn how PR’s and code reviews work. Please don’t worry about how nicely your code looks or if it works or anything like that; the community values passion more than skills since we are confident your skills will improve. And most of all, have fun!
Thanks!
