About Me

I'm a Site Reliability Engineer and Networking specialist with a passion for building scalable, resilient systems. Currently at AWS as a Networking Support Engineer, previously driving automation and reliability at KKCompany.

I love sharing knowledge — from designing workshops to mentoring students in SRE programs. When I'm not debugging infrastructure, you'll find me at hackathons, building apps, or exploring new tech.
