about

Hi, I'm Sanjeeban.

I'm a software engineer with about two years of professional experience building full-stack systems that are reliable, maintainable, and built to scale. I most recently worked at Learning Crew — building web applications, internal platforms, and digital products used in real-world environments. My work spans the full stack: translating product requirements into scalable, practical solutions.

Alongside my professional work, I'm building independent products under my own name, starting with ReciPure — an AI-assisted recipe app currently in pre-launch development. The goal is simple: turn ideas into real, working software.

Beyond code, I create content on YouTube and LinkedIn for students and early-career engineers — helping them navigate the job market and build skills that actually matter. I also write: a personal anthology of poems, prose, and philosophical reflections that I'm slowly compiling.
