About Me

A brief look at who I am and what drives me.

I'm Md. Abdul Kayum, an Android Developer from Barishal, Bangladesh. I completed my B.Sc. in Computer Science & Engineering from Daffodil International University with a strong CGPA of 3.88/4.00.

Currently working as an Android Developer at Archiom, I build Kotlin Multiplatform projects including POS systems, LMS, multi-role management platforms, and payment integrations. I'm passionate about building modern, user-friendly mobile applications and enjoy solving real-world problems through clean architecture and efficient code.

Beyond mobile development, I've published research in IEEE conferences and contribute to open-source projects — including the CMP Country Picker Library.
