I am a student from Ukraine, have bachelor degree in Computer Engineering, and now I'm getting a master's degree.
Also, I have already about 2 years experience in developing on Java, using Spring framework and Hiberante for backend and Angular & Twitter bootstrap for frontend.
Here is last open-source project in which I had partcipated: nwchecker (ACM contest for Ukrainian IT universities students). We used Spring&Hibernate for backend.
I am very familiar with technologies on which is build OpenMRS, so I believe that my productivity will be pretty high.
