Apply Classifier for AI bot
We worked with Bilal, a Senior AI Engineer, to build a RAG-based WhatsApp AI chatbot using Meta WhatsApp Cloud API. He set up the full knowledge base with vector database search so the bot answers accurately from our own data. Delivered on time, professional, and highly skilled. Will hire again.

Verified Meta Tech Provider | Senior AI Engineer | 100% Job Success Score, 20 projects shipped
I build AI systems that work at scale, not just in a demo. If your project needs to handle real users and real message volume, I'm the engineer you want.
As one of a handful of Verified Meta Tech Providers on Upwork, I get faster WABA approvals, higher messaging limits, and direct Meta support — access most freelancers building "WhatsApp bots" simply don't have. I build across all three Meta channels: WhatsApp, Instagram, and Facebook Messenger, plus Telegram.
WHAT THAT MEANS FOR YOU
→ AI agents on WhatsApp, Instagram, and Facebook Messenger that handle 2,000+ real customer conversations a day, with full qualification and CRM handoff
→ RAG pipelines that retrieve the right answer instead of hallucinating one
→ LLM agent systems on LangChain, LangGraph, and CrewAI running in production, not just in a notebook
→ Meta Business API integrations backed by Verified Tech Provider status
→ Full-stack AI SaaS delivery — FastAPI, Django, React, GCP, Docker — architecture to deployment, one person, no handoffs
RESULTS SHIPPED
✅ WhatsApp AI agent for a Saudi automotive marketplace — full customer qualification and CRM handoff, live in production
✅ AI-powered property management backend — scalable multi-tenant architecture
✅ RAG + Kafka real-time pipeline — live document intelligence system
✅ Telegram AI bot integration — delivered in under a week, 5-star rated
I WORK BEST WITH
SaaS founders who need an AI layer built fast and right, not prototyped and abandoned.
Gulf and MENA businesses automating customer communication at scale across WhatsApp, Instagram, and Messenger.
US and EU product teams who need a senior engineer embedded directly in their stack.
If your project involves real complexity — multi-tenant systems, high message volume, custom AI reasoning, production RAG — that's where I perform best.
