I'm a Senior Software Engineer focused on AI/LLM product engineering. I build production AI systems end-to-end — from RAG pipelines and agent architectures to deployment and observability.
Currently building tamy.ai: a production LLM-powered product serving real users — architecting the entire backend, AI pipeline, and infrastructure.
