AI Engineer | Computational Linguist
I build LLM agents, tool-calling workflows, evaluation pipelines, and API-integrated AI systems. Welcome to my personal portfolio — here you'll find my projects, research, and professional background.
About Me
I'm an AI engineer and computational linguist who builds LLM agents, tool-calling workflows, evaluation pipelines, and API-integrated AI systems. I'm completing an M.A. in Linguistics with a Computational Linguistics concentration at San Francisco State University, following a B.A. in Linguistics from UC Santa Cruz.
My work sits at the intersection of language and engineering. At SFSU's ECOLE Lab I research how large language models simplify complex texts and how AI-generated simplifications differ from human language processing. Outside of research I build production AI agents — including a first-place hackathon winner — and ship full-stack services and Linux infrastructure through my company, QubeMC. I work primarily in Python and modern NLP/ML toolkits, and I'm actively seeking opportunities in AI and NLP that pair linguistic insight with technical innovation.
