About Me

I am a Cloud Infrastructure Engineer based in Singapore, currently focused on AWS and Azure environments, Terraform-based infrastructure automation, Linux systems and day-to-day cloud operations.

My work includes setting up multi-account AWS environments, managing hybrid connectivity, improving monitoring visibility, supporting migrations and troubleshooting production issues.

Before moving deeper into cloud infrastructure, I spent more than 10 years working across web development, hosting, Linux/Windows servers, DNS, SSL, CMS platforms and client-facing technical support.
