I'm Himangshu Sikder

I care about interfaces that are simple to use, and about data that is labeled carefully. Both decide whether a product actually works.

I'm a Bachelor of Computer Applications student at Narula Institute of Technology in Kolkata, graduating in 2027. I build front-ends with React, Tailwind, HTML and CSS, and I focus on forms, navigation and the small details that make a page easy to use.

I spent three months as an AI intern annotating and reviewing text datasets used to train generative AI models. It taught me how much a model depends on consistent, careful labeling.

Right now I'm learning cloud and cyber security, starting with AWS Solutions Architecture and a security workshop.
