#1 AI Engineer & Full Stack Developer | Python, LLM, RAG, React

Zero negative reviews, ever. Every client I've worked with has left me at 100% Job Success. Share your biggest operational bottleneck, manual process, or tedious workflow slowing your business down. I will build a production-ready AI system, automated workflow, or full-stack application that works for you 24/7. Send me an invitation or a message and I'll reply with a personalised Loom video showing exactly how I'd help. Not a ChatGPT copy-pasted proposal. I'm an AI Engineer and Full Stack Developer, 9 years in senior software engineering and leadership roles. A quick snapshot: • Top Rated Plus, 100% Job Success Score, zero negative reviews • AWS Certified & Anthropic-certified (Claude API, MCP, Claude Code, Agent Skills) • Worked with Inc. 5000 companies, building production-grade AI apps for them • AI running live across 15+ Saudi government ministries at under 5% hallucination Most AI prototypes never make it to production. They hallucinate, leak data, or fall over the moment real users show up. My focus is the opposite — RAG pipelines, Agentic RAG, Agentic Systems, Multi-agent, LLM integration, and AI agents that ship, stay accurate, and survive an audit. And because I'm full-stack, I build the whole product around them (React, Next.js, Python, Node) — not just an AI layer I hand off and disappear. A few things I've actually shipped: • 15+ Saudi ministries — RAG over 7,500+ documents, 85%+ correct, under 5% hallucination • YourTeacher.ai — scaled 0 to 50,000+ users in 31 languages with LLM tutors and real-time voice • 1,000-franchise network — custom RAG took financial answers from 40% to 95% accurate, leads up 35% • Diesel Laptops — RAG over 160,000+ repair procedures, diagnostic time cut 85% • US personal-injury firm — HIPAA-compliant AI that turns a 2-3 hour demand letter into minutes I've shipped in government, healthcare, legal, EdTech, e-commerce, and telecom — so I get compliance, and I get the difference between a demo and something people depend on. How I work: • Live in production in about 8-10 weeks • Hallucination held under 5% with proper grounding and evals • Weekly updates so you always know where things stand • ~40% lower AI running costs through model and token optimisation • 30 days of support after launch Honest estimates, clean handovers, and I own the outcome. My stack: Python, FastAPI, AWS · OpenAI, Claude, LangChain, LangGraph, MCP · vector DBs (Qdrant, Pinecone, Weaviate) · Next.js, TypeScript, Node for full front-to-back builds, with clean API integration across all of it. Machine learning, NLP, computer vision, fine-tuning, deployment, monitoring — I cover the whole path. If you want AI and full-stack work that reaches production and stays there, send me a message and let's talk. Expertise: AI engineer, full stack developer, Artificial Intelligence, AI Agent Development, Agentic AI, API Integration, AI developer, Python developer, React developer, Next.js developer, Node.js developer, JavaScript, machine learning engineer, LLM developer, RAG developer, generative AI developer, AI agent developer, LangChain developer, FastAPI developer, prompt engineer.
