Summary
🤩
Rockstar🎓
Top SchoolDavid Tressel is a Principal Senior System Analyst with 15 years in senior roles and a software career stretching back to the early 1980s, currently delivering systems engineering expertise at Raytheon Intelligence & Space from Torrance, CA. He brings deep low-level and full-stack experience—evidenced by open-source contributions to Khronos projects like WebGL and WebGPU, where he implemented transform feedback tests and a WebGPU workload simulator used for performance testing. Known for pragmatic problem solving, he has a track record of improving rendering pipelines, fixing deprecations, and adapting build processes to modern deployment targets such as GitHub Pages. A Harvard-trained physicist by background, he combines analytical rigor with hands-on coding (or, as his GitHub bio puts it succinctly, “I multiply matrices”). Colleagues rely on him to translate complex requirements into testable, performant systems and to mentor teams through long-lived programs and evolving web graphics standards.
