Hi, I’m Sein Him Law, an Independent AI Engineer focused on LLM systems, production-grade RAG pipelines, and tool-enabled agents. I design scalable memory architectures, multilingual embeddings, and retrieval strategies that keep essential context alive across long conversations and multilingual environments. I enjoy turning complex data problems into reliable, customer-facing systems, from end-to-end platform development (AWS, GCP, serverless, React/TypeScript) to ML pipelines and analytics, always with a bias for measurable cost savings, robust monitoring, and responsible AI governance.…Hi, I’m Sein Him Law, an Independent AI Engineer focused on LLM systems, production-grade RAG pipelines, and tool-enabled agents.
