About Me

Engineering software, solving problems, and sharing technical knowledge.

Engr. Md Monjur Bakth Mazumder

Software Engineer | Technical Author | Competitive Programmer | AI/ML Enthusiast

I am Engr. Md Monjur Bakth Mazumder, a software engineering professional and Computer Science and Engineering student at Sylhet International University (SIU). My interests span software development, algorithmic problem-solving, technical writing, and emerging technologies. I enjoy turning ideas into practical projects and continuously improving my engineering skills.

My software development interests include modern web technologies, frontend-focused application development, and building maintainable, user-centered digital experiences. I also practice competitive programming using languages such as C++ and JavaScript, with a focus on algorithms, data structures, and logical problem-solving.

Beyond development, I create technical learning resources and publish educational content. Through my Medium articles and technical books, I aim to explain programming concepts clearly and document practical learning experiences. I am also developing my knowledge of Python, data analysis, data visualization, AI, and machine learning.

I use platforms such as GitHub to organize projects and share code, while my technical writing and publications help me communicate what I learn. My long-term goal is to grow as a well-rounded engineer, build useful software, and contribute to the developer community through both code and educational content.
