DuncanB Brandt

I’m a Senior AI Engineer with 10+ years building production machine learning and deep learning systems across healthcare, media, and eCommerce. I specialize in LLM/RAG applications, computer vision, NLP, multimodal learning, and time series forecasting, and I led R&D exploring GraphRAG resulting in two patents.

At Curai Health, I led R&D for Clone M&A and improved core matching functionality using GraphRAG and emerging LLM technologies. I built a generative AI recruiting product with an RAG-based MVP that auto-generates job postings, added keyword/style customization, and implemented multiple security measures against prompt injection. I also developed LangChain bots and chat-based document interaction, deploying containerized, API-exposed services for rapid iteration.

Previously, at Smart Data and HCLTech, I developed ML/DL pipelines for metadata extraction and multimodal tagging, built predictive and real-time vision systems, and engineered data infrastructure supporting 100M+ users and 10x growth. I prepared FDA submissions, authored scientific manuscripts, presented to executives/investors, and improved production performance—such as boosting AWS inference by 60%. I bring strong MLOps discipline (ETL, Airflow, Docker/Kubernetes) and hands-on leadership, including mentoring teams of 6+.
