Most AI automation breaks two weeks after delivery. A demo chatbot that hallucinates, an n8n automation that dies on the first malformed input, an AI agent nobody can maintain. The problem isn't AI — it's that it wasn't built like production software. I'm Fawaz, an AI automation specialist, n8n automation expert, and AI agent developer with 5+ years in backend and automation engineering. I build AI agents, AI chatbots, LLM-powered automation systems, and end-to-end workflow automation solutions that run in production — with real error handling, logging, orchestration, monitoring, and API integration — not prototypes that fall over when a client touches them. Proven track record: 100% Job Success Score Consistently earning 5-star reviews A few results from real builds: A 6-person marketing agency (Google Workspace + Calendly + Slack + Trello + CRM) won back 20+ hours/week — no new hires, no heavy code A creative agency cut client onboarding time 60%; another hit 3× content output with the same team Workflows tuned to a ~0.1% error rate, with 60–80% lower processing cost versus the manual process they replaced I work with teams across real estate, legal, accounting, and healthcare — regulated, document-heavy industries where accuracy, auditability, and clean handover actually matter. That combination — AI model integration plus real software engineering — is what separates automation that demos well from the operating system your business actually runs on. I work with LLM technologies including the Claude API (Anthropic) and OpenAI API (ChatGPT / GPT-4o) daily, building AI systems with Node.js, Python, Go, PostgreSQL, Redis, custom Python scripts, APIs, and automation frameworks. 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 𝘄𝗶𝘁𝗵 𝘆𝗼𝘂 I communicate clearly in plain English, give you a clear scope and estimated timeline up front, and I'm available for long-term collaboration — not a drop-and-disappear handoff. You always know what's shipping and when. 𝗪𝗵𝗮𝘁 𝗜 𝗯𝘂𝗶𝗹𝗱 Workflow automation and n8n automation: AI lead generation, CRM automation, email automation, Airtable automation, Google Sheets automation, data scraping, reporting pipelines, and integrations connecting 400+ apps through n8n. I also handle Make (formerly Integromat), Zapier workflows, and Zapier-to-n8n migrations to reduce subscription costs. AI automation with n8n, Zapier, and Make: Real business process automation including document processing, invoice extraction, email classification, social media automation, AI-powered lead qualification, and internal workflow orchestration. AI agent development and LLM applications: As an AI agent builder and agentic AI developer, I create fully autonomous AI agents and AI agent n8n workflows using Claude API, OpenAI API, and ChatGPT API, with agent frameworks like LangChain, AutoGen, and CrewAI — including function-calling agents, multi-step orchestration, and human handoff. This includes sales assistants, technical support agents, internal operations agents, and AI agents for crypto and fintech platforms. RAG (Retrieval-Augmented Generation) and knowledge-based AI systems: I build RAG-powered chatbots and AI assistants connected to your documents, databases, and internal knowledge bases — allowing LLMs to provide accurate answers using your own business data instead of relying only on general model knowledge. AI chatbot development and chatbot integration: Customer support chatbots with RAG, conversational AI for websites, WhatsApp Business automation, Telegram bots, and custom AI assistants integrated into existing business systems. AI voice agents: Inbound and outbound AI calling systems using ElevenLabs, Vapi, Retell AI, Bland, and Deepgram, with Twilio / WhatsApp Business API for SMS and voice — including appointment booking, lead qualification, customer support, and follow-up workflows. AI model integration and backend development: API development, custom backends using Node.js and FastAPI, webhooks, custom n8n automation nodes, third-party API integrations, secure handling of API keys and credentials, clear API documentation, Python scripts for automation logic, and LLM evaluation workflows. Prompt engineering and AI evaluation: Designing prompts, testing LLM outputs, improving reliability, and ensuring AI automation stays accurate and on-brand at scale. 𝗛𝗼𝘄 𝗶𝘁 𝘄𝗼𝗿𝗸𝘀 You describe the process you want automated and your tech stack, or the AI system you want built. I map the workflow, design the architecture, build the automation, integrate the required APIs and LLM models, test against real data and edge cases, and document everything so your team can operate it without depending on me. If you need an AI automation specialist, automation engineer, or n8n automation expert who builds production systems — AI agents, RAG chatbots, LLM applications, voice AI, or workflow automation — send me a message. Describe the process or idea, and I'll reply with a clear plan and a fixed quote.
