Senior🎓
Top SchoolAlexander Sivura is a Principal Machine Learning Engineer with a decade of experience building production AI systems focused on healthcare data integrity and operational impact. He has led AI teams at HealthTap and Health Gorilla, shipping GPT-4–based clinical chatbots, RAG retrieval pipelines, and EHR-to-summary transformations that materially sped clinician workflows and cohort definitions. Based in Palo Alto, he combines hands-on ML engineering (PyTorch, SageMaker, LangChain) with pragmatic data engineering—normalizing clinical data to OMOP and creating large labeled datasets for NER/NEN and duplicate-question retrieval. Notably, he reduced a 1M+ medical question corpus by over 66% via transfer-learned biencoder/cross-encoder pipelines and shepherded projects from research prototypes to enterprise-grade deployments. He holds advanced AI training from Stanford and a strong software engineering foundation from MSTUCA, blending research-informed approaches with product-minded execution.
