Seattle, Washington, United States
Summary
🤩
RockstarJeff Parsons is a seasoned consultant and software engineer with over 11 years of professional experience and a deep legacy of systems work dating back to contributions on Microsoft OS components from MS-DOS through Windows CE. He builds reliable, low-level software—device drivers, file systems, compression engines and kernel components—while also applying those skills to data analysis, web design, and media processing for projects like The Oyez Project. As a self-employed consultant based in Seattle, he blends hands-on engineering with flexible client-facing problem solving across infrastructure and content pipelines. Known for writing practical code and enjoying the occasional doughnut, he pairs technical rigor with a tone of approachable curiosity. His background suggests an ability to move between deeply technical systems work and higher-level product needs, particularly where performance, interoperability, and media handling intersect.
