Robiul Islam - Staff Network Engineer

About Me

Professional Journey

With over 12 years in network engineering, I've evolved from managing traditional MPLS core networks to architecting cloud-native infrastructure and implementing enterprise-scale automation.

Currently at ServiceNow as a Staff Network Engineer, I focus on public cloud infrastructure, security compliance, and building automation pipelines that bridge development and operations.

I was the first engineer at TPG Telecom to implement CI/CD for network operations, and I've since continued pushing the boundaries of what's possible with infrastructure automation.

Currently exploring the intersection of AI and network engineering, developing intelligent use cases that leverage machine learning for predictive network operations and autonomous CI/CD pipelines.
