IT SUPPORT SPECIALIST // NETWORK ENGINEER
Hello! I'm Tri Agustian, an IT professional with over 5 years of hands-on experience in network engineering
and technical support. I specialize in designing, implementing, and maintaining robust network infrastructure
for organizations of all sizes. From troubleshooting complex connectivity issues to deploying enterprise-grade
security solutions, I bring methodical problem-solving and deep technical knowledge to every challenge.
My passion lies in keeping systems running smoothly and securely, ensuring teams can work without interruption. I believe great IT support is invisible — when it works perfectly, nobody notices.
