About

A little about me.

I'm based in Hyderabad, working at Tata Consultancy Services, and genuinely enjoy the day-to-day of technology — not just using it, but understanding why it works the way it does.

Most of my time goes into learning something new, going deep enough on a topic to explain it simply, and then actually writing that explanation down. That loop — learn, understand, build, share — is basically how I approach everything technical.

Outside of work hours, that curiosity doesn't really switch off. I'm usually reading up on cloud, databases or DevOps, tinkering with something new, or turning notes into a blog post for anyone else trying to figure out the same thing.

“I believe the best way to learn technology is to understand it, build with it, and share what you learn.”

Hands-On

This is where a lot of my time goes.

A glimpse of the database and systems work behind the scenes — SQL, RAC, ASM and RMAN, exactly as they'd run in production.

Writing

I write about technology.

I enjoy turning things I learn into simple explanations and sharing them online. Writing helps me understand technology better — and hopefully helps someone else learn something new.
