Arjun.
Frontend engineer who obsesses over performance and clean architecture. I've spent the last 4+ years building with React and TypeScript — leading the migration that lifted Qilin Labs' Lighthouse from 58 to 92, cut full page load from ~10s to ~3s, and trimmed the JS bundle from 2.4MB to 720KB. Sole frontend architect at Qilin and author of @astra-ui-lib/core on npm.

I build single-page applications for a living. My own portfolio is plain HTML. Here's why that's not a contradiction — and why most websites shouldn't be SPAs.
