About

Hi, I'm Vaibhav. I work on the part of the web most people never see: the APIs, databases and background jobs that make an app feel instant. When a page loads fast and the numbers add up, that's usually the bit I've been looking after.

Right now I'm at Otulia, a luxury marketplace based in Dubai, building the systems behind its blog, comments and rankings. Before that I spent a year and a half at Cognix (BITS Pilani), where I rebuilt a slow backend until it answered 70% faster for more than 1,500 people.

I learn best by building. My GitHub is full of small apps: a weather app, a COVID-19 dashboard, a WhatsApp clone, a Discord bot. The newest, Ghar Hisaab, replaces the paper calendar on the fridge for keeping track of the milkman and the dry cleaner.

Every now and then I write about what I've learned, mostly React and Next.js, and once about my favourite tracks from The Weeknd's Dawn FM.
