Hi there 👋

I'm Vishnu. I'm a software engineer who likes building things and figuring out how they work.

I've spent most of my career working on distributed systems, AWS and cloud applications. Lately, I've been spending a lot more time with AI, LLMs, RAG, agentic systems and MCP.

I enjoy taking an idea, turning it into a small project, and seeing where it goes. Some of those projects end up being useful. Some are just me satisfying my curiosity.

A few things I'm usually interested in:

  • Building software that can actually survive production
  • Understanding what's happening under the hood, especially with AI systems
  • Playing around with new tools and ideas
  • Travelling and finding places worth going back to

You can find me on LinkedIn or reach me at email.
