Rockstar🎓
Top SchoolMike Grima is a Senior Infrastructure Security Engineer with 11+ years specializing in cloud security and DevSecOps, known for building Python tooling that automates security at massive scale. He has led security initiatives at Netflix, Gemini, and Glean, architecting unique dual-control AWS environments and large-scale GitHub onboarding/enforcement systems. An active open-source contributor, Mike has enhanced widely used projects like moto and Netflix’s Security Monkey and open-sourced Starfleet, reflecting deep hands-on knowledge of AWS services—especially S3, which he treats as a personal specialty. He combines practical engineering (many infrastructure visibility and automation tools) with operational rigor born from securing DoD-grade systems earlier in his career. Based in Pennsylvania, he prefers solving thorny, dynamic infrastructure problems and enjoys sharing lessons learned with the community. A subtle strength: he avoids vendor noise and focuses on implementable, developer-friendly security automation.
