About
I’m an AI Engineer with 5+ years of experience building GenAI, RAG, NLP, and applied machine learning systems. I’ve delivered production pilots and PoCs that moved real business outcomes—building a GenAI sales agent that made customer acquisition 6x cheaper, and developing RAG systems used in workflows processing 1M+ annual applications.
I’m especially focused on reliability: I’ve improved document screening accuracy to 95%+ and accelerated retrieval indexing by 95%+ while preserving 90%+ recall. I enjoy translating CTO-level needs into evaluation benchmarks and infrastructure, and I’ve deployed pilots across Azure and Google Cloud while mentoring engineers through KT sessions and self-service improvement loops.
