The Architect
Sixteen years building systems that scale — storage at Dell EMC, travel
platforms at Deem, virtualization at VMware, and now Apple. I care about
the quiet elegance underneath software that simply works.

The shape of me
The Naturalist & Philosopher
I find clarity in the wild — mountains, forests, the sea. Nature is
where I do my real thinking, and philosophy is how I make sense of what
I find there.
The Companion
Two dogs run the house now — Baahu, my Labrador, and Bran, our Berger
Blanc Suisse. The best engineers here have four legs.
The Family Man
Husband to Subishi, a son, a brother. Everything I build, I build for
the people I come home to.

Four Injuries, Two Medals — Coming Back to Badminton
I started playing badminton at thirteen in Ooty, stopped because of a shoulder injury, and spent years being sedentary. This is what happened after a friend pushed me back onto a court in April 2025 — the first medal in October 2025, the four injuries that followed, and the recovery that led to a second medal.
The heights by great men reached and kept were not attained by sudden flight, but they, while their companions slept, were toiling upward in the night.
