What I'm looking for

I’m looking to work with teams that value collaboration, operational excellence, and practical engineering solutions, especially in enterprise infrastructure, Microsoft technologies, automation, and digital transformation.

At PT GSMS, I worked as a Network Security Specialist, bringing my enterprise IT background to network security. Before that, I worked at PT.Great Giant Pineapple in IT infrastructure and telecommunications, contributing to enterprise technology operations.

At PT.Great Giant Pineapple, I contributed to server administration, telecommunications, infrastructure modernization, and automation. My experience includes supporting environments serving more than 2,500 users and managing over 250 Windows and Linux servers.

I work across Windows and Linux administration, Microsoft 365, identity management, and virtualization. I enjoy troubleshooting complex production issues, finding root causes, and implementing practical solutions that improve reliability and reduce repetitive work.
