About Me

Who I Am

Janhavi Sonurkar — Blockchain developer portrait for About section

I have a Master's in Blockchain Technology and a habit of building things — full-stack apps, backend services, smart contracts, and dApps like AgriChain and ChainPay using React, Next.js, Solidity, Node.js, and REST APIs. At Timchain Labs, I worked with wallet authentication and APIs in a real development environment, which taught me how systems behave beyond tutorials. I'm currently strengthening my backend skills — working with APIs, databases, server-side development, and building complete applications end to end. I'm looking for an entry-level Full Stack, Backend, or Blockchain role where I can build real products, learn from strong engineers, and keep pushing my work further.
