About

  • 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 and Software Engineer at EssenZvita Life Sciences, shipping production web and mobile apps.
  • I've designed, built and launched production apps for startups, like RideAway (10,000+ installs, 800+ bookings): scalable frontends with Next.js and high-performance cross-platform apps with React Native, backed by Node.js, Express, Prisma, GraphQL and Supabase.
  • I'm building ExpoKit, copy-paste UI components, charts and templates for Expo, and publish open-source packages like @expokit/cli, expo-charts, postman-to-api and hover-tooltip. I use AI tooling and LLM APIs to ship faster without giving up clean architecture.
  • Beyond code, I work like a forward deployed engineer: I sit with the client, shape the product, design clean UI with AI tools, and own delivery through launch. I also do technical SEO: structured data, canonicals, sitemaps, Core Web Vitals and AI-crawler files. This site is my playbook.
