Lecturer, Dept. of CSE · BUET
Dhaka, Bangladesh
Hey! I'm a CSE graduate from BUET and currently serving as an Lecturer in the CSE Department at BUET. Over the years, I’ve evolved from a passionate developer and competitive programmer into a dedicated researcher. My interests now lie at the intersection of machine learning, geospatial reasoning, and AI-driven systems. I'm thrilled to share that my recent research work has been accepted at ICML, and I'm actively pursuing impactful questions in the field. While I still enjoy building applications and solving problems, my primary focus is now on advancing research that can drive innovation and deepen our understanding of intelligent systems.

Diculator: All-in-one Android Calculator App
Made a calculator using Android Studio(Java). It looks like an ordinary calculator. But it has some special features. It can be used to make a call or send messages. It can also be used as a stopwatch, timer, counter, alarm clock. You can also send messages to a WhatsApp number without saving the number.
Polygon | OpenGL App
Just a random app to draw polygon using OpenGL.
Lissajous Figure | OpenGL Simulation
Got to know about Lissajous figure from Physics course. Wanted to visualize it.

Tennis game using Pygame
Explored Pygame library and made a simple tennis game with both single player and double player mode. In single player mode, the player plays against the computer. The computer always moves towards the ball.
CSE102 Project: DxBall
First game that I made using OpenGL. This was a term project of CSE102. Three games where divided among 120 students. Pacman, Catch the egg and DxBall. I got DxBall.
Handling Big Numbers using C++
A C++ code to handle big decimal numbers like Java BigDecimal Class. More time consuming than BigDecimal but better functionality and Accuracy.The idea behind the working of this program is that using the traditional method for adding,subdtracting,multiplying numbers, the same method we used in primary classes. And the number is so large that it has been stored in string in the form of separate digits.It can calculate until the total digit of the result is <= string::max_size().
Created a wrapper class String over std::string with extra methods. And took an instance of String in BigDecimal Class.
CSE102 Offline: Curves
First app using OpenGL. This was an offline of CSE102. We were provided with iGraphics.h which was a wrapper over OpenGL. We had to draw some curves using the functions provided in iGraphics.h.
