I like making things work.
I'm Biswajit, a software engineer who started with the backend and somehow ended up caring about the whole product. These days I work across backend systems, frontend, infrastructure, and the occasional design rabbit hole.
Currently building at ITMC Digital, working on whatever interesting problem is in front of me.
