About

My background spans graphic design, web design, and information technology. Through exposure to different fields, I gradually developed a strong interest in networking, systems, and infrastructure. This led me to earn the Cisco Certified Network Associate (CCNA) certification and pursue a career in the IT industry. I am currently working as a Network Systems Validation Engineer, primarily responsible for network and system validation. Outside of work, I continue to explore Linux, Docker, and self-hosted services, while building and maintaining my own technical environment through my homelab. To me, the enjoyment of technology is not just about making something work, but about thinking through how to build systems that are cleaner, more stable, easier to maintain, and more scalable. I am currently expanding my knowledge in DevOps and cloud infrastructure, with the goal of combining my networking and systems background to further broaden my expertise in related technical areas.
