Hello, I'm Nayem. I build the parts of a product you never notice: fast APIs, quiet servers, and deploys that just work.

Currently, I build with Python, React and AWS. I completed my MSc in Software Engineering at Kingston University, London in 2025, with Distinction.

I enjoy turning complex requirements into clean, reliable engineering solutions.

Here are some of my most meaningful builds.
