Rockstar🎓
Top SchoolCorey Schafer is an experienced software engineer with 12 years building data systems, GIS web applications, and developer tooling across academic, government, and private sectors. Based in Belle, West Virginia, he maintains a popular set of development dotfiles and Python-focused code snippets, reflecting a strong emphasis on automation, environment configuration, and performance profiling. His background includes supporting NASA mission data processing at LASP and developing GIS applications with ArcGIS APIs, demonstrating comfort with both scientific data pipelines and geospatial web tech. As a self-employed educator since 2018, he creates free programming videos on YouTube, translating deep technical practices into clear, practical tutorials. He combines hands-on DevOps skills (macOS automation, Brew/Cask, symlinks) with backend Python expertise (memory profiling, logging, SQLite), making him adept at optimizing developer workflows and production systems. Notably, his open-source work reveals a habit of improving his own toolchain first, then sharing those refinements with the community.
