Arjay Gregorio

Hey, I’m Arjay . I’m a software engineer living in Quezon City. I am a fan of photography, technology, and gaming. I’m also interested in web development and programming.

I work extensively with AWS services such as EC2, VPC, EKS, RDS, Route 53, ACM, and Elastic Load Balancers, ensuring performance, scalability, and compliance with security best practices. I also manage Kubernetes clusters both in Amazon EKS and on-premise environments, including cluster setup, YAML deployments, and containerized workloads using Docker.

My experience includes:

• Designing and supporting AWS multi-region architectures
• Windows Server and Linux administration (Ubuntu, RHEL, Amazon Linux)
• Active Directory, Group Policy, WSUS, DNS, DHCP, and RADIUS
• Server hardening, VAPT remediation, and CIS Benchmark compliance
• TLS/SSL configuration and certificate management
• Backup, disaster recovery, and virtualization (VMware, Hyper-V)
