Selected Work & Live Demos

Hands-on examples of how I design backend systems, cloud architectures, and AI-assisted business workflows for enterprise teams.

Live Demo

SmartSupply Agent

AI-powered procurement sandbox. An autonomous agent evaluates inventory, supplier pricing, shipping deadlines, and qualitative risk notes — then decides whether to fulfill from stock, purchase externally, or reject with business alternatives.

Customer Message Classifier

An AI-powered customer message classifier that automatically detects intent (complaint, sales inquiry, shipping inquiry) and routes messages to the right department — with confidence scores and a friendly reply for each case.

  • Zero-shot learning: works immediately without training data
  • Channel-agnostic architecture: same AI core for web, WhatsApp, email, and SMS
  • Currently implemented: web / API endpoint (WhatsApp handlers in repo)
  • Real-time classification with confidence scores

Saves hours of manual dispatch work for customer support teams.
