A little corner of the internet, by me.

Hi, I’m Sai Daya
Shankar.

AI engineer. Full stack developer. Curious human.

I like figuring things out and building things that help. These days, that means AI agents, thoughtful software, and a lot of learning along the way.

Based in the United States · Currently at HIKIGAI

ABOUT ME

A builder.
A problem-solver.
Always learning.

I’m Sai Daya Shankar Giridhar, a software engineer who found his way into AI through building things. I started with web applications and now spend my days working on agents that can reason, use tools, and work together.

At HIKIGAI, I build and evaluate AI for healthcare. That work has taught me to care just as much about whether something is dependable as whether it’s clever.

I have a master’s in Data Analytics Engineering from George Mason University and a background in computer science. This is where I share what I’ve been working on.
