About me

Hey there! I'm Md Rajibul Islam (also known as rajibulcr), a tech enthusiast and B.Tech CSE student with a knack for crafting digital solutions that people actually use. I transform ideas into apps that solve real problems—my Google Play creations have racked up over 5,000 downloads!

I thrive on solving complex challenges through elegant code. When I'm not building apps, you'll find me working on QR-based attendance systems or designing responsive websites. I'm also a bit of a competitive coder (150+ problems on LeetCode) and hackathon junkie who loves leading teams to bring innovative ideas to life.

  • Web Development
