Sarthak Shah
backend / smart contract engineer
I'm a Founding Engineer at MetEngine 
.
I love working with financial systems, game theory and mechanism design. You'll find me building elaborate backend systems, smart contracts, and low-latency distributed infra as weekend gigs.
I enjoy participating in hackathons and have won ~20 of them. Also, in my free time, I obsess over cameras, drones, and bikes.
