Summary
👤
SeniorTess Sluijter-stek is a pragmatic Security Engineer with over a decade of hands-on IT experience across Linux, Unix and Windows environments, specializing in DevSecOps, automation, logging/monitoring and PKI. She thrives on being "thrown at" unfamiliar problems, quickly learning and delivering working solutions while leaving clear documentation and training materials so teams can continue without her. Certified across diverse domains (OSCP, CISSP, RHCE, PSM-I, GCCC, ITILv3), Tess balances deep technical proficiency with strong teaching and community-building skills—she currently teaches Linux+ and is developing a DevSecOps course after recently earning the CKA. Known for a calm, reliable presence in crises, she combines consultant curiosity with steady operational discipline, making her effective in both short-term engagements and long-term improvement projects.
