About the Developer

I'm Karan Kumar, also known online as Ansh Karan (Anshkaran7 on GitHub and itsmeekaran on X and LinkedIn), a full stack developer from India with 2+ years of hands-on experience shipping production web and mobile apps.

I've designed, built and launched 15+ production applications for startups — scalable frontends with Next.js and high-performance cross-platform apps with React Native, backed by Node.js, Express, Prisma, GraphQL and Supabase.

I publish open-source packages like expo-charts, postman-to-api and hover-tooltip (4,618+ downloads combined), and I use AI tooling and LLM APIs to ship faster without giving up clean architecture.

Open to full-time remote roles and freelance projects.
