I build production-grade AI systems in enterprise and personal contexts — RAG pipelines, LLM evaluation frameworks, process automation, and agentic workflows. 5+ years of software development experience including enterprise AI systems at scale.
My background sits at the intersection of industrial engineering and data science. I obsess over the system around the model as much as the model itself.
