• I led implementation efforts to put real-time predictive models in live clinical charts. I was responsible for the entire implementation, from workflow considerations, to infrastructure, to serving scores, to.
• Machine Learning Engineering: Built a robust, high-uptime production pipeline for custom clinical AI models running in the live medical record. Written for Epic, using Python, and leveraging CI/CD in Microsoft Azure.
• Data Science: Co-led a project to predict the risk of hospital acquired injury using patient chart data, achieving high 70s precision and low 80s recall. Designed to drive better allocation of nursing resources for the.
• Generative AI: prompt engineering to extract information from unstructured clinical note data for computational phenotyping, using Azure AISearch and OpenAI.
• Software Engineering: automated key business practices using REST APIs to facilitate major process overhaul.
• Drove the adoption of modern software engineering practices through the organization: moved the team from a sparsely used on-prem instance of Gitlab to having the whole division working in Azure DevOps.Contributions to.

• I worked on the Oracle Data Cloud Identity Graph.Project highlights include:
• Incorporating geolocation data into the modeling layer of the ID graph.
• Rebuilding a record linkage algorithm between incoming and fulfilled datasets, improving quality of the match by 45%, scale by 30%, and standardizing the approach across 1000s of data inputs.
• Evaluating the quality of the graph with a Monte Carlo approach, demonstrating a factor of ~6 improvement of quality relative to a purely deterministic graph.

• Built a comprehensive data classification tool for end users using Apache OpenNLP, Spark, Hadoop, Sqoop, Hive, Python, ElasticSearch, and Java.
• Built of suite of distributed tools to augment publicly available NLP packages.
• Used these tools for information security and control for KPMG as well as data separation for large, multinational clients across millions of documents hundreds of TB in size.
