ChatCart Pro
Most small restaurants and grocery stores in the UAE and India don't have the margin or the technical team to run a custom ordering app. ChatCart Pro meets customers where they already are — WhatsApp — and gives the business an AI chatbot, a voice agent, and a POS-synced inventory, all in one product.
The challenge
Restaurants and grocery stores lose orders every time a phone line is busy, a customer doesn't want to install another app, or a message on social media never gets a reply. These businesses also typically run on a POS system with its own stock numbers, disconnected from any new ordering channel.
I wanted to build something that didn't ask small business owners to change how their customers already behave — people already message businesses on WhatsApp — while still solving the real operational problem of stock going out of sync between channels.
Approach
I designed and built ChatCart Pro around WhatsApp as the primary ordering surface, since it requires zero download and zero behaviour change from the customer. On the business side, the core engineering problem was keeping cart, stock and POS numbers consistent in real time, so an order placed in chat doesn't oversell inventory that was just sold in-store.
I added an AI voice calling agent on top of the chat flow for customers who'd rather call — covering the case where WhatsApp isn't the right channel, like an older customer or a quick phone order — and an AI chatbot for businesses that want a similar experience embedded on their own website, not just WhatsApp.
What I built
A WhatsApp-native commerce platform with POS-synced stock and an AI voice ordering option.
- WhatsApp Cloud API integration for in-chat ordering, no app install required
- Real-time POS stock sync so WhatsApp orders and in-store sales share one inventory source of truth
- AI voice calling agent that takes phone orders and logs them into the same system
- A white-label AI chatbot product for restaurants' own websites
- Restaurant-specific flow combining WhatsApp + voice + POS ordering in one package
Outcome
ChatCart Pro is live with a pilot supermarket in Tamil Nadu, India, validating the core WhatsApp-plus-POS-sync model in a real retail environment.
As the founder and sole product/engineering lead on this, I own everything from the WhatsApp integration logic to the voice agent's conversation design to the POS sync architecture — the kind of full-stack ownership that doesn't come up in an employed design role.
