Node.js services & webhook gateways
Node where it earns its place: webhook gateways that verify signatures and translate a platform’s protocol, and a multi-tenant messaging back end on Express and MongoDB.
The systems behind it

WhatsApp-Native Commerce Platform
A multi-branch store where the entire storefront is a WhatsApp conversation
Customers order exclusively through WhatsApp — there is no app and no website to visit. A stateful flow engine drives the conversation, a separate Node gateway handles Meta protocol translation and signature verification, and two Laravel dashboards give head office and each branch live control over orders, catalog and working hours.
Role: Full-stack — both services, dashboards, flow engine and deployment

Omnichannel AI Assistant
One webhook, one app, every channel — WhatsApp, Messenger and Instagram
An automated reply system serving every page and every WhatsApp number a company owns from a single deployment. The AI layer is abstracted behind a provider interface, so the model can be swapped without touching conversation logic — and the Meta app-review surface (privacy policy, terms, data deletion) ships with it.
Role: Sole engineer — AI abstraction, channel routing and Meta review
