Summary
👤
Senior🎓
Top SchoolJohn Evans is an HPC Support Systems Administrator with 13 years of experience specializing in scientific and image data formats (NetCDF, HDF5/HDFEOS, FITS, JPEG2000) and a strong background in MATLAB, C/C++, and Python. He has a long history of operational support for 24/7 scientific services (NOAA, UCAR) and has modernized legacy workflows—rewriting Excel/VBA processing into Jupyter and netCDF for the University of Washington. At MathWorks he led the Image and Scientific Data Formats team, shipping format support and managing third-party integrations, and he continues to contribute to open-source scientific Python projects such as SciPy and SunPy (notably improving JP2 handling via glymur). Based in Washington, D.C., he blends systems administration, production monitoring, and developer-focused toolmaking to keep scientific pipelines reliable at scale. An oft-overlooked strength is his ability to translate domain-specific data formats into robust, testable code and metadata workflows used by research and operational communities.
