AI Engineer · Agentic Systems & Healthcare AI

// Hello, I'm

Ahmad Muhammad

I build production-grade AI systems — from medical speech recognition and RAG-powered clinical tools to autonomous multi-agent workflows and LLM-powered backends that run daily in healthcare and enterprise environments.

What I Do

Services

End-to-end AI engineering — from medical AI deployment to autonomous agentic systems.

🤖
Autonomous AI Agent Development
Design and deploy multi-agent systems using CrewAI, LangGraph, and n8n. Agents that autonomously research, decide, route, and deliver — without human intervention.

LLM Integration & RAG Pipelines
Implement RAG pipelines with vector embeddings (pgvector/Supabase) for semantic search, intelligent document retrieval, and AI agents that query your own data.

Portfolio

Work

Production AI systems I've designed, engineered, and deployed.

// AI Developer · Python, FastAPI, MedASR, MedGemma, Flutter · 2026
E-Prescription AI App – Medical Speech Recognition
Healthcare AI

Built a production e-prescription Flutter app where doctors speak and AI transcribes in real time. Deployed MedASR (medical speech recognition) and MedGemma (Google's medical LLM) locally, exposed both as REST API endpoints via FastAPI, and connected to the Flutter mobile app. Outputs two results: a transcribed prescription text and AI-generated clinical suggestions — with the doctor retaining full control to accept or reject.

IMC AI Doctor – Intelligent Patient Analysis System
Healthcare AI

End-to-end patient analysis platform for IMC Hospital. n8n pulls data from Microsoft SQL Server across 6 parallel streams (labs, radiology, pharmacy, discharge notes, vitals, pathology), custom JavaScript merges and structures it by admission, generates comprehensive HTML clinical reports, chunks and embeds them into Supabase/pgvector, and a Claude Sonnet AI agent answers physician queries via RAG in real time.

CrewAI Content Pipeline – 4-Agent Autonomous System
Agentic AI

Architected a 4-agent CrewAI pipeline in Python — Researcher, Writer, Editor, and Manager — that autonomously researches topics via DuckDuckGo, drafts articles based on a style guide, polishes content, and emails the finished output. Integrated Groq API for fast LLM inference and implemented a production workaround for a CrewAI/Groq API compatibility bug.

FinSage – AI Banking Agent
AI Agent

AI-driven banking assistant that analyzes customer profiles and recommends the most suitable bank via email. Implemented a custom RAG pipeline with Supabase/PostgreSQL (pgvector) for semantic profile matching. Engineered an autonomous multi-agent state-machine managing full account-opening lifecycles via webhooks and WhatsApp Business API.

Omnichannel AI Order Management Engine
Full-Stack

Multi-channel order ingestion gateway consuming Facebook, Instagram Graph, and WhatsApp Business APIs. Built a scalable Node.js/Express backend on Railway with JWT auth and strict input validation. Implemented LLM text classification to detect purchase intent from unstructured social feeds — reducing manual processing overhead by 100%.

IMC Management Reporting Automation
Enterprise

Large-scale automated reporting workflow comprising 60+ interconnected nodes processing 500+ records daily across 60+ parallel data streams. Designed a highly concurrent distributed fan-out architecture with conditional routing and error-handling. Reduced manual reporting effort by 70% through scheduled triggers and automated delivery.

PDSRU Disease Alert System
Healthcare AI

Automated disease surveillance system with 3 parallel alert workflows (Main, PDSRU, DDSRU). Scheduled triggers fetch live disease data via HTTP APIs, custom JavaScript nodes classify severity, then automatically route HIGH PRIORITY and STANDARD alerts to health authorities via Gmail and WhatsApp simultaneously — zero manual intervention.
