Engineer / Builder
Sarthak Khare
I like building things that work — and keep working at scale.
I'm a full-stack engineer currently leading engineering at Cobox. I joined as a frontend developer and now own the entire stack — frontend, backend, system design, DevOps and AWS infrastructure across the Cobox ecosystem.
Beyond Cobox, I've shipped products with IIT Indore, Wikimedia, and Indian SaaS startups, and freelanced 10+ production apps for clients across India, Australia and the Philippines. I also build open-source tools for the Wikimedia community.
