Web application development company in Delhi NCR

A web app first suits a product people use at a desk or open through a shared link. A mobile app first suits work built around the camera, location or daily notifications. Start with the way people will use the product: a link to a shared workspace calls for a different first build from a product centred on the phone’s camera.

For hosting, a managed platform such as Vercel, Supabase or Firebase reduces setup and server upkeep. Running directly on AWS or Google Cloud gives you more control and can cost less at scale, but it also leaves more operations work. For a product serving several customers, a shared database is simpler to run; a separate database for each customer suits enterprise buyers with strict isolation or data-location requirements.

We build with TypeScript across the front end, back end, database and APIs, using a stack such as Next.js, React, Node.js and PostgreSQL. Next.js and React suit rich interfaces with one language across front and back end. Laravel, Rails or Django are options for teams already skilled in PHP, Ruby or Python.

If your product takes payments in India, decide how customers will pay and who will aggregate those payments. UPI supports person-to-merchant payments, while non-bank entities aggregating customer payments for merchants need authorisation from the Reserve Bank of India. We set up subscription payments around the agreed checkout requirements, including a UPI option where needed and an authorised payment aggregator where the model requires one. The payment flow needs to fit your plans as well as the way customers pay.

Bring whatever you have already decided, along with the questions you still need to settle.

  Rebuilding common components

  Use proven services for sign-in, billing and permissions where they fit, so the budget is not spent recreating parts users rarely notice.

• !

  Treating every payment event as new

  Payment webhooks can arrive more than once or out of order. Handlers need to skip events already processed and avoid depending on their order.

• !

  Releasing without a safety net

  Use a staging environment and test backups so a release mistake does not immediately become a live incident.

• !

  Launching without product analytics

  Track sign-ups, activation steps and feature use from the first release, so you have evidence of where users get stuck.
