Hi, I’m Shrikanth. I’m a Senior Software Engineer at Microsoft, where I work on Copilot Enterprise.

I’ve spent more than nine years in frontend engineering, building products at several top tech companies along the way.

CompleteFrontend is where I share what that experience has taught me: one concept at a time, in plain language, with code you can run, step through, and change until the idea clicks. JavaScript is the first guide; more topics are on the way.
