About
I am a Full-Stack AI Engineer and QA Specialist bridging the gap between advanced technology and reliable software. My work spans from building high-conversion business platforms to engineering complex Hybrid AI Systems - most notably the Ponca Translator, a platform combining RAG, NLP, and Generative AI for language preservation. With a "Quality-First" approach rooted in professional testing, I ensure that whether I'm building Autonomous Agents or Scalable Web Apps, the result is robust, performant, and bug-free.
