Hire the Best Neo4j Developers in Cairo, EG

I build custom AI backends, RAG systems, and knowledge graph pipelines that help teams turn large, messy datasets into reliable, searchable, and explainable AI products. My work goes beyond simple chatbot wrappers. I focus on building production-ready systems with clean backend architecture, accurate retrieval, strong data pipelines, and practical cost control. I can help you with: Knowledge Graphs & GraphRAG I design and build knowledge graph systems using tools like Neo4j and Cypher. This includes entity extraction, relationship mapping, deduplication, and turning complex documents or domain-specific text into structured, connected data. Custom RAG Pipelines I build retrieval systems using vector databases such as Qdrant and FAISS, combined with metadata filtering, semantic search, reranking, and source-grounded answers. The goal is to make retrieval accurate, explainable, and useful in real business workflows. AI Backend Development I develop clean and scalable backend services using FastAPI, async Python, Docker, and modular architecture. I can integrate multiple LLM providers such as OpenAI, Claude, DeepSeek, or local models, while keeping the system flexible and easy to maintain. Custom Multi-Agent Systems When needed, I build lightweight multi-agent orchestration in plain Python instead of relying heavily on frameworks. This gives better control over logic, prompts, token usage, retries, routing, and cost. AI System Optimization I can review or rebuild existing AI prototypes to reduce hallucinations, improve latency, lower API costs, and make the architecture easier to debug, monitor, and scale. Why work with me? I care about building AI systems that are reliable, maintainable, and practical. That means I focus on: -Clear backend architecture -Accurate retrieval and source citations -Cost-efficient LLM usage -Deterministic and testable pipelines -Clean code that can be extended later -Real production needs, not just demos Typical projects I can help with include: -Building a domain-specific Q&A system over documents -Creating a Knowledge Graph from unstructured text -Improving an existing RAG pipeline -Migrating an AI prototype into a production-ready backend -Designing custom AI workflows for research, legal, technical, educational, or internal business data -Auditing your current AI architecture for accuracy, cost, and scalability

I am a Senior AI Engineer with 6 years building production AI systems, most of it working directly with American startups. I am a native English speaker, so communication is never a translation layer between me and the client. I do not just prototype AI features. I ship full systems that survive real users, real load, and real edge cases. A few examples: Built a Legal RAG Platform serving 100K+ users in production for 18+ months, cutting support queries by 60% through grounded retrieval instead of hallucinated answers. Designed and owned full AI architecture for a B2B insurance intelligence platform: hybrid vector and keyword search, LangGraph based multi-agent workflows, a Neo4j graph database, and DuckDB pipelines for structured data. Built a 1,024 question LLM as judge evaluation system that took model accuracy from 50% to 80%, so quality is measured, not assumed. Built a Multi-LLM Chatbot Builder, a Chatbase style SaaS supporting OpenAI, Claude, and Gemini with Stripe billing and multi-tenant workspaces. Built voice AI systems (Vapi plus N8N) that handle real inbound calls and book appointments directly into CRMs like GoHighLevel and Mindbody. Full stack: Python, LangChain, LangGraph, LlamaIndex, FastAPI, Next.js, React, TypeScript, PostgreSQL, Pinecone, Weaviate, pgvector, AWS (ECS, Lambda, Bedrock), GCP, Docker, CI/CD. I work independently, own architecture decisions end to end, and communicate directly with weekly progress updates, no middleman, no black box. If you need someone who can take an AI idea and turn it into something reliable enough to run your business on, that is the work I do.
