Building reliable, high-fidelity software solutions for educators, schools, and administrators worldwide.
At Raji's Lab Technologies LLP, we believe that administrative tasks shouldn't take time away from what truly matters—teaching and leading. QR Attendee was born out of a desire to eliminate the archaic, time-consuming process of paper attendance.
We've dedicated ourselves to providing a suite of offline and online tools that bring speed, accuracy, and security to classrooms and boardrooms across the globe. Our vision is to empower educators with technology that is invisible, seamless, and incredibly fast.
Whether offline or in the cloud, we design our systems to ensure user data remains encrypted, local, and protected from unauthorized access.
We optimize every button and scanner so that checking in a classroom of 50 students takes seconds, not minutes. Time is the ultimate currency.

Driven by a deep passion for solving real-world problems through elegantly written code, Md Rajibul Islam (or simply Rajibul to our community) founded Raji's Lab to create tools that make a tangible difference in people's daily workflows.
With QR Attendee, Rajibul's vision was incredibly straightforward: make attendance tracking so fast and seamless that it practically runs itself. Rejecting the bloat of traditional enterprise software, he architected an app focusing purely on speed, offline reliability, and user-centric design.
Today, that vision continues to evolve and empowers thousands of educators and administrators across more than 50 countries worldwide.
