# about
I'm Jay, a full-stack developer from India. I like the whole journey from an idea to something people can use, with a soft spot for the backend: clear APIs, thoughtful data models, and systems that hold up beyond the demo.
Right now I'm building Billzzi, billing and POS software for Indian shops that still write bills by hand. It runs on Android and desktop from one Hono API on Cloudflare Workers.
I started in 2022 with HTML, CSS and JavaScript. On the side I'm reading through Bitcoin internals, and I spend time with my cats.

Billing and POS for Indian shops, replacing handwritten bills. Catalog billing, GST, customer khata, stock, staff roles, thermal printing, and WhatsApp-ready invoices. The Android app is live; a Windows and macOS desktop app on the same API is on the way.
