Hi, I’m a software engineer with a strong passion for building and optimizing backend systems, working with data systems, and designing efficient databases. I genuinely enjoy solving challenging problems—whether it’s optimizing existing systems, analyzing data to create new solutions, or debugging critical production issues under tight deadlines. Problem-solving gives me a sense of purpose, and I find joy in bringing structure and efficiency to complex systems.
When I’m not coding, I love spending time with my cat babies—they never fail to brighten my day with their antics. I also enjoy sketching as a creative outlet and volunteering to give back to the community, which keeps me grounded and inspired.
Regarding my background, I earned my Master of Mathematics (MMath) in Computer Science degree from the David R. Cheriton School of Computer Science at University of Waterloo, where I had the privilege of working under the supervision of Prof. Semih Salihoglu. Before that, I completed my Bachelor’s in Computer Science and Engineering (CSE) from Bangladesh University of Engineering and Technology in 2016.
Thanks for stopping by! Feel free to explore my site to learn more about my work, projects, and what drives me.
