About

Software engineer and open-source contributor focused on generative AI and modern web development. I build production AI systems, custom LLM pipelines, and agents that deliver measurable business outcomes. My expertise spans full-stack applications, typed APIs and integrations, automation systems, and AI tooling platforms. When I'm not building, I'm watching UFC and probably building something UFC-related.
