Hi, I'm MOBALLIG

Software Engineering student, competitive programmer, and builder of practical web and mobile experiences.

01 — Introduction

A little about me.

I turn ideas into practical, reliable software.

I'm Moballig, a Software Engineering student at Daffodil International University focused on backend development and artificial intelligence. I build web and mobile products, REST APIs, and AI-powered solutions while strengthening my craft through competitive programming.

I also document what I learn, mentor other students, organize technical events, and contribute to open-source projects.
