I build websites, web apps and mobile apps that hold up in production — not demos.
Mostly Next.js and React on the front, Node and Postgres behind it, React Native when it needs to be on a phone. Recent work: a full agency platform with Razorpay + UPI payments, GST invoicing, role-based admin and the deployment running it.
What you get: code you own, a repo you can hand to anyone, and honest scoping. If your idea is better solved a cheaper way, I will say so before you pay.
I reply within a few hours (IST) and I do not disappear mid-project.
New Delhi. Tell me what you are building.

FAQ
What tech stack do you use?
Next.js and React on the front end, Node.js on the back end, PostgreSQL for data and TypeScript throughout. If your project uses a different stack, tell me and I'll confirm whether it's a fit.
Can you work on my existing web app?
Yes. Share the repository and what needs to change. I'll review it and send a fixed quote before starting.
Do I own the code?
Yes. You get the full repository at handover, with no licence fees and no lock-in.
Is hosting included?
Hosting isn't included, but I'll recommend the right option for your budget and deploy the app for you.
My project is bigger than the Premium package. Can you help?
Yes, that's common for SaaS. Message me with your feature list and I'll send a custom offer with a fixed price and milestones.
How are updates and maintenance handled?
Bug fixes for 30 days after delivery are included. After that, updates and maintenance can run as a monthly retainer or as fixed-price custom offers, whichever suits you.
