About
I'm Souvik, founder and COO of Shotlin and Opslin. I sit where product, engineering and operations meet: deciding what to build, shaping how it feels and making sure it ships and keeps running.
With Shotlin we have built quick-commerce platforms for Surat and Hyderabad, an electronics marketplace, a garment-care marketplace in Pune, retail AI and a game. With Opslin we are making it simple to deploy software on a server you own.
