Hamza Khan

I’m a Senior AI Engineer and Full-Stack Developer with 12 years of production experience building backend systems, AI-enabled platforms, and full-stack SaaS products. I specialize in AI-native architectures—RAG pipelines, multi-agent workflows, and LLM integrations—along with the backend infrastructure that makes them reliable at scale. My strongest work lives at the intersection of AI/LLM engineering and backend systems: OpenAI and Anthropic Claude integrations, LangChain and LlamaIndex workflows, and vector database-driven retrieval using Pinecone, pgvector, and Weaviate. I design production systems using Node.js, TypeScript, Python, FastAPI, and PostgreSQL, and I build microservices and event-driven APIs that can handle real-world load. I’ve designed, built, and deployed production-scale solutions across HealthTech, FinTech, MarTech, Renewable Energy, Real Estate, and HRTech. From agent orchestration platforms and RAG layers to HIPAA-compliant communications and AI-enabled operations dashboards, my focus stays consistent: scalable architecture, clean execution, and measurable outcomes.
