About
Born and raised in Bangalore.
Started programming with Turtle Graphics. Fell in love with C++.
First computer was a Lenovo ThinkPad X240. Great keyboard, loud fans.
Love computers, books, free markets, and playing football.
Went to Ramaiah. Studied computer science, the closest thing I could find to astrophysics.
Accidentally landed at Halodoc, building healthcare software in Indonesia.
Accidentally entered crypto, then made a conscious 10-year bet on blockchains.
Built crypto infra at Unmarshal and Shardeum. Contributed to Ethereum through Teku.
After five years in infra, moved closer to consumers at Zora.
Fell in love with software all over again when agents started getting good.
(First time living through another move up the abstraction stack.)
Huge movie buff, with favourites in Hindi, English, Tamil, Kannada, Telugu, and Malayalam.
