About me

Hi, I'm Amritendu Bhattacharjee, a Senior Software Engineer who builds secure, scalable applications. On a typical day I turn business requirements into live features, join architecture discussions, review code, and run sessions for junior engineers and interns. I care about software that holds up in the real world, so I try to get the security and failure modes right before the code ships. Away from work you'll usually find me with my dog, building personal projects, or reading anything from human evolution to science fiction. I think art matters as much as any other field: commerce and science build the mind, but art helps build the soul.

React application to display weather reports of major cities in India.

Recently, the Reflect buli-in object has been enabled for javascript to inspect shape and properties of an object. Even then Typescript which is a superset of javascript does not support this feature by default.

AI Text Hue takes in an RGB color value (like 255,87,51) and tells you if the dominant text color should be black or white. Under the hood, it trains a neural network on a dataset of RGB values paired with the ideal text color, and uses that model to make predictions.
