Hello!

I'm Harsh, a developer who enjoys building things and understanding what happens behind the scenes.

I work across the stack, but I'm particularly interested in backend engineering - designing APIs, working with databases, building real-time systems, and connecting services.

Beyond coding, I'm part of the Core Team at Innogeeks, where I serve as Web Lead. I've also been part of the organizing team for InnoHacks 4.0, collaborating with fellow developers to bring the hackathon to life. I'm a third-year Information Technology student at KIET Group of Institutions, based in India and looking for opportunities to build meaningful software.

Currently exploring
  • Backend architecture
  • Distributed systems
  • AI agents
