About Stephen J. Barr
I have a strong set of skills centered around data engineering and machine learning. As a machine learning engineer, I can manage full machine learning pipelines, from accessing databases, large scale data manipulation and feature engineering, model training, deployment and management. Key skills include usage AWS, Spark, and machine learning platforms.As a data scientist, I have a strong grounding in machine learning and data science theory. I have worked as a data scientist in a variety of settings, including highly regulated settings such as healthcare, banking, and education administration. My academic background is in applied mathematics and optimization. I pride myself in taking a disciplined and pragmatic approach to machine learning, starting with the simplest solutions while keeping in mind future requirements for performance, accuracy, maintainability and scalability. As a functional programmer, I have a strong knowledge of Haskell and it is my language of choice for most projects. I have used Haskell to build domain specific languages to model particular problems, such as patient encounters with a research hospital. I have a strong knowledge of Python and R.
