AI Engineer · Senior Software Engineer
LLM Applications, Multi-Agent Systems & Voice AI
I build applied LLM systems that survive production — multi-agent pipelines, RAG assistants and real-time voice agents — on top of five years of multi-tenant SaaS and AWS architecture.
I'm an AI-focused Senior Software Engineer with 5+ years of professional experience, including four-plus years building GCC enterprise logistics systems that process thousands of shipments daily across Oman, the UAE and Saudi Arabia.
I initiated and lead the AI programme at one of Oman's largest logistics platforms — shipping RAG chatbots, AI copilots, and a production multi-agent document-AI system that replaced most of a 12-hour daily manual data-entry workload. I proposed it, architected it, and took it to production.
Independently, I built and run AI Caller, a multi-tenant AI call-agent SaaS that answers live phone calls with hallucination-resistant, knowledge-grounded responses. Solo build, from the Twilio bridge through to billing and onboarding.
What I've learned from both: the model is the easy part. Grounding, evaluation and failure taxonomies are what separate a demo from something a business can bill against. I'm also a Section Leader at Stanford's Code in Place programme, and I mentor the engineers on my team through code review and architectural guidance.
The stack behind the work below, grouped the way I actually use it.
Three builds worth reading in detail — a multi-agent document-AI pipeline in production, an AI voice-agent SaaS I built solo, and a piece of pure backend engineering.
Five agents reading handwritten waybills into structured orders
A production multi-agent pipeline that reads handwritten bilingual Arabic/English shipping labels into structured orders, cutting a 12-hour daily data-entry workload to 2–3 hours of review. Built on a fixed LangGraph state graph with one agent per responsibility.
An AI receptionist that answers real inbound calls, 24/7
A SaaS where any business self-serves an AI phone receptionist that answers real inbound calls in a natural voice — live in production on AWS. Founder and solo build, from the telephony bridge through to billing and onboarding.
Millions of records, streamed at low memory cost
A production-grade REST API for locale-based translations: Controller → Service → Repository architecture, Redis tag-based cache invalidation, and cursor-based export streaming millions of records at low memory cost.
Five years of continuous ownership, plus teaching and freelance work.
Promoted from Software Engineer to Senior Software Engineer. Five years of continuous ownership of the same multi-tenant logistics SaaS platform.
