Freelance MERN stack developer for Bangalore startups.
I'm Sumit Kumar, a freelance MERN stack developer based in Vashi, Navi Mumbai. I work remotely with Bangalore startups on MVPs, admin panels and features for existing MERN apps. I don't have an office in Bangalore; everything is done remotely in your team's tools. Admin panels start at ₹7,999; web apps are quoted after a call.

01 — Bangalore
Working remotely with Bangalore teams
Most startup work is either an MVP built from zero or extra capacity on an existing codebase. For both, I work inside your GitHub, your issue tracker and your chat.
Same time zone, overlapping working hours, and async updates for anything that doesn't need a call.

What clients say
We came to Sumit with a fairly complex e-commerce setup in mind — payments, shipping, the works. He got it all working smoothly and was quick to fix anything we flagged after launch.
