About Me

Hi! I'm Mahmudul Hasan Sayan, a Software Engineer based in Dhaka, Bangladesh. I specialize in building scalable web applications using .NET technologies and cloud-native architectures.

With a Master's degree in Computer Science and over 3 years of professional experience, I work on enterprise solutions involving microservices, containerization, and DevOps practices. I'm passionate about clean code, performance optimization, and continuous learning.

This is my digital space where I share my thoughts on software development, architecture patterns, and things I learn along the way. When I'm not coding, you'll find me exploring new technologies or contributing to the developer community.
