About

I'm Debarati. I build websites and apps, and I'm picky about how they feel.

Debarati Seal

Picky means motion that lands at the right moment and layouts that still work on a small phone. I'm happiest on the frontend, mostly in Next.js and TypeScript, but I've built whole products on my own, database and all. I'm in my final year of B.Tech IT at RCCIIT, Kolkata, graduating in 2027. Next, I want a startup team where I can build a feature all the way through and watch people use it.I'm happiest on the frontend, in Next.js and TypeScript, but I've built whole products on my own, database and all.
