👤
Senior🎓
Top SchoolJohn Flickinger is a cybersecurity-focused software engineer with 11 years of experience blending offensive security, research, and full-stack development across government labs and industry. Currently at IBM X-Force Red after serving as a Red Team advisor for the Federal Reserve, he specializes in penetration testing, adversary emulation, and security R&D informed by hands-on exploit development. His background includes applied research at Sandia National Laboratories and practical penetration testing at the Army Research Laboratory, giving him a rare mix of classified-grade rigor and product-minded delivery. Early freelance web development work—such as adding 4-player chess to Chess.com—and a student full-stack role show he remains an active, pragmatic builder, not just a tester. He holds a BS in Computer Science and an MS in Analytics from Georgia Tech, reflecting strong analytical grounding behind his offensive techniques. Based in El Paso, he maintains a public technical presence (johnnyvf24.github.io) that signals continual curiosity across software and security.
