Hi, I’m Raian
I’m a software engineer based in Berlin, Germany. I write about software engineering concepts — system design, object-oriented programming, data structures, databases, and networking — primarily in Bengali, because quality technical content in Bengali is still rare.
My goal is simple: make software engineering concepts accessible to Bengali-speaking learners worldwide, explained the way I wish someone had explained them to me.
