Most AI projects break two weeks after delivery. A demo chatbot that hallucinates. An automation that dies on the first malformed input. An AI agent nobody can maintain. The problem isn't the AI, it's that it wasn't built like production software. I'm Fawaz, a senior full stack AI developer with 5+ years in backend and automation engineering. As a Python and Node.js developer, I build AI-powered web apps and SaaS platforms end to end, the LLM/agent layer and the application around it, that actually run in production: clean, maintainable code, real error handling, logging, orchestration, monitoring, and API integration. Not prototypes that fall over the moment a client touches them. That combination, AI model integration plus real software engineering, is what separates something that demos well from the system your business actually runs on. Proven track record 100% Job Success Score, consistent 5-star reviews Workflows tuned to a ~0.1% error rate, 60–80% lower processing cost vs. the manual process A 6-person agency won back 20+ hours/week; a creative agency cut onboarding 60% and hit 3× content output with the same team Work across real estate, legal, accounting, and healthcare, regulated, document-heavy industries where accuracy, auditability, and clean handover matter What I build Full stack web apps & SaaS platforms, from AI SaaS MVPs to production systems: clean, responsive React / Next.js front ends (desktop, tablet, mobile), backends in Node.js, Python (FastAPI / Django), PHP (Laravel), and Go with PostgreSQL, Supabase, and Redis, plus auth, Stripe/subscriptions, webhooks, third-party API integration, Docker, and CI/CD so it ships and stays up. Backend development & APIs — as a Node.js, Python, and PHP/Laravel backend developer / backend engineer, I build scalable REST APIs, custom backends, AI backends, and data pipelines with proper testing, logging, and documentation. LLM applications & AI agents — autonomous and function-calling agents, multi-step orchestration, human handoff, using the Claude API (Anthropic) and OpenAI API with LangChain, AutoGen, and CrewAI. This is LLM and machine learning integration for sales assistants, support agents, and internal ops agents. RAG & knowledge systems — chatbots and assistants grounded in your own documents, databases, and knowledge bases, with vector search, reranking, and hallucination controls — so answers come from your data, not the model's guesses. AI chatbots & voice agents — RAG support chatbots, WhatsApp/Telegram bots, and inbound/outbound voice (Vapi, Retell, ElevenLabs, Deepgram + Twilio) for booking, qualification, and follow-up. AI automation & workflow automation — as an AI automation agency of one, I build n8n, Make, and Zapier workflows for AI lead generation and qualification, CRM and GoHighLevel automation, email and social media marketing automation, document processing, web scraping, and reporting across 400+ apps, including n8n + Supabase builds and Zapier→n8n migrations to cut subscription cost. Prompt engineering & LLM evaluation — as a Claude prompt engineer, I handle prompt design, output testing, and reliability work so the AI stays accurate and on-brand at scale. How I work I communicate clearly in plain English, give you a clear scope and estimated timeline up front, follow best practices, and I'm available for long-term collaboration — not a drop-and-disappear handoff. You describe the process or product; I map the architecture, build it, test against real data and edge cases, and document everything so your team can operate it without depending on me. Send me a message with what you're building, and I'll reply with a clear plan and a fixed price quote.
