Online stores and ordering apps that sell more

I build e-commerce that fits how you actually sell: an online store for retail customers, a B2B portal where shops reorder in bulk, or a mobile app for your regular buyers. Catalogue, cart, payments, invoices and delivery, all connected to one backend you own.

04 FAQ

Common questions

Can Gajraj build an e-commerce website or online store?

Yes. He builds online stores and ordering apps end to end: catalogue, cart, checkout, payments, order tracking and an admin panel, for retail, wholesale and D2C businesses.

Can he build a B2B or wholesale ordering app?

Yes. For Neem Karoli Sales, a beverage wholesaler, he built Android apps for retailers and delivery staff, a web admin and the API, with online payments and GST invoices.

Should I use Shopify or a custom store?

If a ready-made platform like Shopify fits your needs, he will tell you. A custom build makes sense for B2B ordering, special pricing rules, your own mobile app or deep integrations with your other systems.

Which payment gateways does he integrate?

Razorpay and Cashfree in production, plus wallets, vouchers and referral rewards from his work on Pickup Coffee's apps.
