Hanan A.

I am an AWS Certified Generative AI Developer – Professional and Senior Systems Architect with over 6 years of experience shipping enterprise-grade applications. If your existing AI pipeline is hallucinating, your API handoffs are failing, or you need a complex multi-agent system built securely from scratch, I step in to design the architecture and execute immediately. Core Specializations & Technical Outcomes: - Autonomous Multi-Agent Architectures: I design resilient, state-controlled agentic workflows using LangGraph, CrewAI, and rigid Pydantic validation gates. I specialize in building autonomous agents capable of multi-step business orchestration, secure tool-calling, and CRM routing. - Advanced Production RAG: I engineer secure Retrieval-Augmented Generation engines over dense unstructured enterprise data, relational databases, and vector infrastructure (Pinecone, pgvector, AWS OpenSearch) with strict privacy boundaries. - Voice AI & Omnichannel Automation: Production experience deploying real-time conversational voice agents (Retell AI, Vapi) natively paired with asynchronous webhooks across Meta WhatsApp API, Twilio, and n8n/Make automation tracks. - Cloud-Native Full-Stack Engineering: Building high-concurrency, zero-latency backends (Python FastAPI, Flask, Node.js) and clean, responsive interfaces (Next.js, TypeScript, Tailwind CSS) deployed inside isolated Docker containers on AWS. The Production Stack: - AI & Orchestration: Model Context Protocol (MCP), LangGraph, LangChain, LlamaIndex, Claude 3.5 Sonnet, GPT-4o, AWS Bedrock - Backend & Databases: Python (FastAPI, Django), Node.js, PostgreSQL, MySQL, Redis, Supabase - Vector & Cloud: Pinecone, pgvector, AWS OpenSearch, Docker, ECS, Lambda, S3 - Frontend: Next.js, React, TypeScript, Tailwind CSS Client Feedback: "Strong technical expertise, reliable, and delivers high-quality work on time." "Very professional and easy to work with. Delivered exactly as expected." I work as a strategic technical partner, not a blind task-taker. I will actively audit your technical requirements, flag potential architectural bottlenecks before they manifest, and deliver clean, modular code that your engineering team can easily manage long-term.
