Who Am I?

Charlie Leo

Hi, I'm Charlie Leo Prima Putra Marpaung — an Software and Web Developer based in Jakarta. I graduated in September 2016 from Budi Luhur University with a Bachelor's degree in Information Technology, majoring in Information Systems.

I have good communication skills in Indonesian and English. With experience across software development, Android, and back-end systems, I'm ready to work in teams or individually to deliver quality solutions.

"The biggest goal of a self-motivated developer is to produce high-quality software all the time, regardless of the obstacles and self-doubt encountered."
