WHO I AM
I'm a Full-Stack Web Developer currently working as a Junior Executive at Pakiza Software Limited in Dhaka, Bangladesh. I specialize in building scalable applications with modern architectures.
My passion lies in real-time communication systems — from WebRTC peer-to-peer connections to live streaming pipelines using RTMP and HLS protocols. I've delivered enterprise-grade solutions for live streaming, e-commerce, and business platforms.
I hold a B.Sc in Software Engineering from American International University, Bangladesh (CGPA: 3.61), and I continuously push my limits by exploring new technologies and best practices.
Beyond code, I believe in clean architecture, team collaboration, and writing software that not only works but is maintainable and performant.
