i spend my weekdays working in Portkey and doing side projects on weekends. I have been lucky to discover the work of inspiring people from around the world early in my life, which has greatly influenced my own work and ideas

i’m most active on X (sometimes more than i would like)

things i believe

• the cost of energy will come close to 0 in the coming decades
• number of iterations is the key to successful things
• good artists copy, great artists steal
• agency is the most important thing if intelligence becomes democratized

cool people

i like the idea of writer builders mentioned here

there are few things that can give you asymmetric returns in life. this website is one experiment to get asymmetric returns. hopefully someone is interested in what i write and it lands into something tangible. or maybe my future wife reads this, i don’t know

here’s a list of cool people on the internet that inspired me to write this (with some web presence):

Anu Atluru · Paras Chopra · Paul Graham · Alexey Guzey · Dwarkesh Patel · Patrick Collison · Nat Friedman
