AI Engineer building production LLM systems with open-weight models. I combine applied AI, backend engineering, and full-stack delivery to turn model capabilities into reliable products.
I am the Founder & AI Engineer at Crelyvo and a Full Stack Developer at Kern-it Global. My work spans structured LLM output, model routing and fallback, evaluation, guardrails, human-in-the-loop workflows, APIs, cloud systems, and product interfaces.
