From idea to AI-powered products

I'm a Full-Stack Developer pursuing a Bachelor of Software Development at BYU-Idaho. I build production AI applications — LLM-powered chatbots, RAG systems, and content pipelines — turning models like Llama 3.3 and Claude into products people actually use.

I also architect automation ecosystems — n8n, custom AI agents, and API integrations that replace manual ops with self-running infrastructure. My stack centers on Next.js, TypeScript and Python, backed by PostgreSQL and Supabase — and yes, I've shipped on-chain too.
