About me
I’m Rishab.
I'm a product engineer who enjoys taking an idea from a rough concept to a product people actually use. I own the whole path — understanding the problem, shaping the experience, and building the interface, backend, database and deployment — with a focus on practical tools and clear user experiences.
Most of my work centres on Next.js, TypeScript and PostgreSQL, including SaaS products, websites for businesses and AI-assisted tools.
