Khurram S.

I build enterprise .NET platforms, AI agent pipelines, and WhatsApp automation systems that run in production. My longest engagement is 6+ years with a single client, growing from 4 modules to a 9-module field operations platform. I have shipped WhatsApp AI agents handling 1,000+ daily bookings across 30+ businesses, RAG pipelines with confidence gating, and agentic workflows on Azure.
