Hi, I am Nafisa!
I am a software engineer and a passionate coder with an inclination to data systems, databases, and data in general. I love solving challenging problems, optimizing systems, analyze data to build new systems or improve existing ones, and solving production issues by critically analyzing and debugging several connecting systems with a race against time. While I enjoy my work very much, I love to sketch and do volunteering at different places 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.
