Hi, I am Nafisa!
I am a software engineer and a passionate coder with an inclination to backend system engineering, data systems, and databases. I love solving complex challenges, optimizing systems, analyze data to build new systems or improve existing ones, and solving production issues by critically analyzing and debugging with a race against time. While I enjoy my work very much, I love to sketch and do volunteering to give back to the community during my leisure time.
Regarding my background, I have a Master of Mathematics (MMath) in Computer Science degree from the David R. Cheriton School of Computer Science at University of Waterloo, supervised by Prof. Semih Salihoglu. I completed my B.Sc. in Computer Science and Engineering (CSE) from Bangladesh University of Engineering and Technology in 2016.
