Geospatial Developer building software to solve spatial problems using (predominately) Python.
Professional Experience
2023.07 - present
Python Developer
Oak Ridge National Laboratory, Oak Ridge, TN.
- Development and maintenance of Python package repositories for scientific workflows.
- Guide software engineering and data science best-practices for handling large geospatial modeling and prediction projects.
- Collaborate directly with senior science and engineering staff to meet project needs and deadlines.
- Enhance and extend existing tools and workflows for speed and scalability in a production environment.
Key Projects:
Global Building Intelligence
Built production workflows for existing scientific code repositories allowing for speed and scalability. Collaborate closely with scientific modeling staff to develop a complete rewrite of Bayesian model software, which is the core of the project’s prediction framework.
Nautical Charts
Developed software for file input of S57 format geospatial data following modern Python software development idioms. This package includes testing and benchmarking for standard installation and Docker containerization. The software is the core file loading tool for inputs to the machine learning framework used to integrate changes detected in the marine landscape.
