About Hammad
AI Engineer | Python, Machine Learning, RAG, LLM & OpenAI API
100%
Job Success
Karachi, Pakistan - 5:58 am local time
AI Engineer specializing in production-grade LLM, RAG, and AI agent systems. 8 years in software, Top Rated Plus on Upwork with 100% JSS, AWS Certified AI Practitioner and Anthropic-certified (MCP, Claude API, Claude Code, Agent Skills), $200K+ earned across 66 jobs, and AI live across 15+ Saudi government ministries at under 5% hallucination and 85%+ accuracy.
I build Artificial Intelligence that survives real users, real load, and real compliance not demos. Most AI prototypes never reach production because they hallucinate, leak data, or fall over at scale. My focus is the opposite: RAG (Retrieval-Augmented Generation) pipelines, LLM integration, and AI agents that ship, remain accurate, and hold up under audit.
💼 WHAT THAT LOOKS LIKE IN PRODUCTION
🏛️ GCC Government Contact Center: a production RAG system serving 15+ Saudi ministries. 7,500+ documents on a Weaviate vector database with hybrid retrieval, under 5% hallucination and 85%+ answer correctness.
✅ YourTeacher.ai: scaled from $0 to 50,000+ active users across 31 languages, with LLM tutors, Whisper speech recognition, ElevenLabs voice, and real-time pronunciation feedback; built for a 5M-subscriber creator.
✅ IFPG (1,000+ franchise network): custom RAG plus advanced prompt engineering lifted financial answer accuracy from 40% to 95%, cut cross-contamination 80%, raised qualified leads 35%, and cut support time 40%.
✅ Diesel Repair Chat (Diesel Laptops): AWS Bedrock RAG with BGE embeddings and Qdrant over 160,000+ repair procedures; replaced dropdown filters, cutting diagnostic search time by 85% and lifting satisfaction by 40%.
🃏 Pokemon TCG Intelligence: a Python/FastAPI platform processing 260,000+ price points daily across 65,000 cards, with LLM-powered grading ROI that surfaced 3x more profitable opportunities.
⚖️ SettleWing (US personal injury law): HIPAA-compliant legal AI that turns 2-3 hour demand-letter prep into minutes, at 95%+ extraction accuracy across all 50 states with Medicare fee integration.
✅ SmartHistory.ai: HIPAA-grade clinical AI intake with voice-enabled patient interviews and structured medical summaries for providers.
✅ Dynasty Pulse: a real-time Claude Opus summarization pipeline with RSS automation that cut content latency 98%, from 15+ minutes to seconds.
✅ CarGentur (Germany): an AI sales chatbot rebuilt into a full CRM, lifting engagement 40% and conversion 20%.
✅ TitoAI (telecom): a WhatsApp-native LangGraph agent for airtime, data bundles, and crowdfunding across all major Nigerian networks, cutting transaction time 80%.
🩺 Vital Connect (healthcare): LLM diagnostics with Computer Vision imaging and real-time EHR sync, HIPAA-compliant, cutting diagnostic time 40%, errors 60%, and lifting doctor productivity 70%.
✅ RESPONSE BPO: GPT-4o and Whisper support automation with real-time transcription, dynamic call routing, and multilingual voice at high volume.
✅ Angel Therapy: a GDPR-compliant microservices platform with Deepgram transcription and LLM summarization that cut processing time 90%.
🤝 WHY CLIENTS STAY
I ship to production in roughly 8-10 weeks, hold hallucination under 5% with grounding and evaluation baked in, send weekly Loom updates so you always know where things stand, engineer for roughly 40% lower AI running cost through model and token optimization, and back every launch with 90 days of post-launch support. You get honest estimates, clean handovers, and an engineer who owns the outcome. Domains I've shipped in include government, healthcare (HIPAA), EdTech, legal, e-commerce, and telecom, so I understand compliance, data handling, and the difference between a demo and a system people depend on.
🛠️ CORE STACK
My core stack is Python, FastAPI, and AWS, with OpenAI API, Claude, LangChain, LangGraph, and MCP for LLM, AI agent, and Generative AI work, PostgreSQL and vector databases (Qdrant, Pinecone, Weaviate) with BGE and OpenAI embeddings for retrieval, and Next.js/TypeScript when a full-stack front end is needed. I cover the full path: Machine Learning, Deep Learning, NLP, Computer Vision, Data Science, LLM fine-tuning, and AI model integration, through to deployment on Docker, monitoring, and cost control.
