Rockstar🎓
Top SchoolMarcos Oviedo is a Principal Engineer and Windows security specialist with 20+ years of systems and low-level engineering experience and seven years focused on security and product-building. Currently at NinjaOne he architects mission-critical Windows internals features for endpoint management and previously led exploit-prevention work at McAfee and contributed system-level improvements to the popular Fleet open-source agent. He founded Stagerlabs to provide Windows internals consulting, offensive tooling, and AI-driven vulnerability research—work reflected in personal projects like Memhunter, SysmonX, and ETW support for osquery. Marcos blends deep reverse-engineering expertise with hands-on product architecture, from embedded telecom systems to enterprise security platforms, and has a knack for turning complex OS telemetry into practical detection and automation. An infosec nerd by GitHub bio, he often surfaces non-obvious attack surfaces through static analysis and custom tooling that scale real-world detection and response.
