What I'm looking for

I’m looking for remote cloud infrastructure and operations roles where I can apply my Linux, Windows, networking, and security background while building and operating AWS/Azure environments. I’m especially interested in infrastructure automation, reliability, troubleshooting, observability, and secure cloud operations using technologies such as Terraform.

I'm an infrastructure engineer focused on AWS, Linux, and production operations. I use Terraform to build secure AWS infrastructure across IAM, VPC, EC2, CloudWatch, and CloudTrail, backed by extensive experience in troubleshooting, patch management, system hardening, monitoring, incident triage, and root-cause analysis.

I'm a U.S. citizen with full U.S. work authorization, currently based in Bangkok and open to fully remote opportunities worldwide. I'm flexible across U.S., EMEA, and APAC working hours.

My professional background spans Windows Server, Red Hat Enterprise Linux, VMware/virtualization, networking, and secure infrastructure operations. In prior roles, I maintained 97%+ uptime through proactive monitoring, patching, capacity planning, preventive maintenance, and resilience improvements. I've also led security-focused work involving SIEM monitoring, RBAC, VLAN segmentation, ACLs, system hardening, and vulnerability remediation.

I hold AWS Certified Solutions Architect – Associate, AWS Cloud Practitioner, CompTIA Security+, and CompTIA Linux+. Recent Terraform and cloud infrastructure projects are available on GitHub.
