I'm passionate about solving complex problems in system infrastructure, cloud architecture, system design, and DevSecOps. I’m especially excited by the challenge of building and securing large-scale, distributed systems with a focus on high availability, scalability, fault tolerance, and security. Designing systems that integrate diverse technologies and enable seamless microservice communication—particularly within Kubernetes and AWS EKS—drives my enthusiasm.

I have hands-on experience with a wide range of AWS services (ECS, EKS, VPC, RDS, EC2, CloudFormation, CloudWatch, S3, and more). I'm also proficient in Infrastructure as Code (IaC) using Terraform and Ansible for cloud resource provisioning. Additionally, I’ve built secure CI/CD pipelines with Jenkins, Docker, SonarQube, Trivy, OWASP, ArgoCD (GitOps), GitHub, Kubernetes, and DockerHub.

Through a combination of coursework, certifications, and practical experience, I’ve developed strong expertise in AWS infrastructure. In my role as AWS Solution Architect and DevOps Engineer for the MD-Sensei medical platform (Engineering Senior design, goal is to develop mobile app as a AI medical mentor for third world country), I deployed ECS (Fargate) containers integrated with RDS (PostgreSQL) and application load balancer, configured Route53 DNS with SSL via ACM, and implemented secure VPCs with public/private subnets, NAT gateways, and tightly controlled IAM policies. I’ve also leveraged AWS CloudFormation for repeatable infrastructure deployment and used CloudWatch to monitor application health, performance, and logging across services. I also engineered CI/CD pipelines using GitHub Actions, SonarQube, and AWS ECR to streamline deployments and security.

Beyond infrastructure, I bring strong DevSecOps experience in automation and observability using tools like Terraform, Ansible, Jenkins, Prometheus, and Grafana. In a Netflix Clone project, I provisioned and configured AWS resources—including VPC, EKS, EC2, Internet Gateway, subnets, and security groups—using Terraform and Ansible. I implemented GitOps practices using ArgoCD and Helm for Kubernetes deployments, with full monitoring and security checks built in with Prometheus, and Grafana. These projects reflect my ability to plan, build, and scale AWS-native applications in alignment with operational and security best practices. I also have experiences in OS and Computer Network, such as RHEL, CentOS, Ubuntu, TCP/IP, DNSSEC, etc.
