Summary
👤
Senior🎓
Top SchoolJohn Gresl is a systems engineer with a decade of hands-on experience building tooling and analyzing software vulnerabilities for defense and research organizations, currently at Peraton after roles at Northrop Grumman. He blends a strong computational physics and applied mathematics background (UC Irvine, Northwestern) with six years of research-grade Python development and additional proficiency in C++, MATLAB, and Java. His work spans software, hardware, and lab systems—designing circuits, soldering, machining custom metal parts, and diagnosing vacuum systems for experimental detectors. Notably, he has implemented microsecond-level signal analysis algorithms and GUI tools for characterizing silicon photomultipliers and particle-detection experiments. Equally comfortable leading teams or producing high-impact results independently, he maintains an active project portfolio on GitHub (SyntaxVoid) that reflects his cross-disciplinary problem-solving approach.
