I'm Sarthak. I studied computer science at IIIT Dharwad and graduated in 2025. By day I'm a software engineer at a startup in Gurgaon.
In 2026 I started making my own apps in the evenings and on weekends. I like small, focused products that do one thing well, and I'm still learning most of what it takes to make them work as a business.
