About Me

I'm a Computer Science & Engineering student, software developer, and technology professional working across full-stack development, artificial intelligence, and research-driven computing.

I currently work as a Junior Software Developer at Kode By Kraft, contributing to production web applications, frontend engineering, backend systems, API integrations, and client projects. Alongside my software development role, I serve as Head of Technologies & Digital Systems, taking responsibility for technology initiatives, digital infrastructure, and software-driven solutions.

I'm pursuing my B.Sc. (Hons.) in Computer Science & Engineering at Metropolitan University, Sylhet, Bangladesh, with an expected graduation in July 2027.

Beyond application development, I'm interested in machine learning, deep learning, climate data, geospatial computing, remote sensing, and explainable AI. I enjoy connecting software engineering with research and practical problem-solving to build useful, reliable, and scalable solutions.
