At 1000xDev, I develop SaaS applications across frontend and backend systems using Next.js, NestJS, FastAPI, and PostgreSQL. I also work on asynchronous background workers that process more than 2,000,000 database records daily.

At RegisterKaro, I delivered frontend interfaces and backend APIs supporting 5,000 client registrations, and automated legal registration workflows with Puppeteer-based web scraping. At Visra Enterprises, I developed a digital signature SaaS platform and integrated Razorpay payments.

I also published Arbyte, an open-source AI terminal CLI, and created SiteGenie, a platform that turns natural-language prompts into live websites. I’ve solved 1,000 Data Structures and Algorithms problems and contributed to GSSOC 2025.
