Hi @jayasanka!
This is a great start and will really help set the stage for your GSoC project. There are a few different conversations happening in the community right now where DHIS2 integration and/or reporting has come up.
One is the current discussion around a community solution for ETL/ELT, with a stand up planned for later this month.
The other is taking place as a part of our COVID-19 Response. Integrating with DHIS2 Aggregate is an important part of that response and you might find it useful to join some of those conversations.
