Back to original languageAbout Arthur
I design and deploy applied AI systems capable of reliably interacting with complex business environments. My work lies at the intersection of artificial intelligence, software engineering, and product, with a focus on AI agents, neuro-symbolic systems, and their integration into real-world applications.
I am involved in the entire value chain: designing agent architectures, RAG and GraphRAG pipelines, integration with business tools, implementing safeguards like human-in-the-loop control and granular permissions, as well as reliability, monitoring, and observability topics. My goal is to build useful, robust, and scalable AI systems.
