Ayman H.

Full Stack & Automation Engineer

Hi, I’m Ayman 👋 I’m a former Lead Engineer at Zillow and a university CS professor turned AI & Automation Engineer. I design LLM-driven systems, RAG knowledge pipelines, and end-to-end automations using Make.com, n8n, Zapier, Python, Node.js, and custom APIs. If your business relies on manual workflows or scattered data, I build the systems that remove bottlenecks and scale cleanly. What I build 🚀 LLM + Knowledge Systems ✨ Retrieval-Augmented Generation (RAG) pipelines ✨ Internal AI assistants trained on your documents ✨ Agent workflows for multi-step decision making ✨ AI knowledgebases using Google Drive, Notion, PDFs, CRMs ✨ Voice → text → structured processing pipelines ⚙️ Process Automation & Orchestration 🔧 Multi-step Make.com & n8n workflows 🔧 Cross-platform automation (billing, calendars, forms, CRMs) 🔧 Automated onboarding and approval flows 🔧 Document generation and contract automation 🔧 Python/Node microservices to extend no-code tools 📈 Lead Gen, CRM & Sales Automation 📬 Lead scoring and qualification automations 📬 Multi-channel outreach (email/SMS/DM) 📬 CRM setup + workflows (HubSpot, Close, Airtable, Notion, GHL) 📬 Lead enrichment, routing, tagging, funnel automation 🧩 Custom Engineering 🛠 API integrations (REST, webhooks, OAuth) 🛠 Django/React internal tools 🛠 Real-time systems (WebSockets, event routing) 🛠 ETL pipelines: ingestion → cleaning → storage → AI 🛠 Enterprise-grade scripting: Python, Node.js Why work with me 🏢 Enterprise engineering background Former Lead Engineer at Zillow → built production systems for millions of users. 🎓 10+ years teaching Computer Science I explain clearly, document cleanly, and architect systems thoughtfully. ⚙️ Rare hybrid skillset Most automation freelancers can only use no-code tools. I combine no-code + full-code + LLM engineering so your systems are reliable, scalable, and clean. 💬 Clear communication Direct, transparent, fast. You always know what’s happening. If you need ✔ LLM-powered internal assistants ✔ RAG knowledge systems ✔ Make.com or n8n automation ✔ CRM + lead gen automation ✔ SaaS or internal workflow orchestration ✔ Microservices or API integrations ✔ Systems that remove manual work ✔ A builder who can architect the full end-to-end solution I can help from strategy → architecture → implementation → deployment. Looking forward to working with you Ayman Hajja, PhD 🚀
