ABOUT
Technical depth, built through practice.
I’m an IT and cybersecurity professional building deeper expertise across identity, cloud administration, systems, and security operations. My work is grounded in roughly three years of technical support, identity, and security operations experience—reinforced through hands-on labs and public projects.
I care about understanding how systems work, documenting what I learn, and turning repetitive or complex workflows into useful automation. Alongside my technical career, I build software concepts and digital products that solve practical problems.
