Backend-focused software engineer and team lead.
I'm Biswajit. I work mostly on the backend: data models, service boundaries, and the small decisions that decide whether a product is still easy to change a year later. I have an eye for design, lean on AI tools to move faster, and care that what ships is actually good.
Currently backend developer and team lead at ITMC Digital, and learning how to build systems that hold up in the AI era.
