Hi @DUSHIME,
Welcome to the DHIS2 Community! If this is your first time, do well to introduce yourself to the team [here](https://community.dhis2.org/t/introduce-yourself/15).
Now for your question, if you you have not coding experience, you may want to first learn basic software development knowledge. You’ll find a roadmap outlined here to help you equip yourself with the prerequisite knowledge depending on what development path you want to take (web/android).
