My Professionals activities are around four topics

• Insurance management system (https://openimis.org)
• Clinical decision system
• DHIS2
• Health technology management systems

on my own time I develop and maintain module for the opensource ERP called dolibarr

I am doing development to help my own productivity or for fun but I am not a professional developer; I know the basic of C, C++, Python, Java and I have a bit of experience on PHP
