About

Sairaj

Hey, I'm Sairaj — a software engineer who enjoys building things for the web.

I studied CS in college, but most of what I know about web development is self-taught. What drew me in was the instant feedback — write an HTML file, double-click, and you can see what you built. That simplicity hooked me.

Currently, I work at Contentstack, where I'm building auto-save and real-time collaboration features for the core entry editor.

I have a soft spot for build tools and developer experience. A project with a bad DX? Can't stand it. A well-configured bundler? That's my kind of fun.

This site is where I share things I've built and write about what I'm learning.
