What I'm looking for

I’m looking for a team where I can own end-to-end AWS platform delivery—Terraform IaC, GitOps CI/CD, Kubernetes, and observability—while continuously improving reliability, security, and cost efficiency in production.

I’m a results-driven DevOps & AWS Cloud Engineer with 5+ years of experience designing scalable, secure, and cost-optimized cloud infrastructure. I’m hands-on with Terraform IaC and multi-account AWS architecture—VPC, EKS, ECS, IAM, RDS—to deliver reliable, repeatable deployments across production environments.

My strengths include GitOps-based CI/CD delivery with GitLab CI/CD, ArgoCD, and GitHub Actions, plus Kubernetes operations on EKS and containerized workloads with Docker. I’ve implemented observability using Prometheus, Grafana, Loki, Alertmanager, Sentry, and ELK Stack to improve detection and incident response, including cutting MTTD by 60% and reducing response time by 40%.

I also focus on measurable business impact—driving AWS cost optimization (~25% AWS spend reduction) through right-sizing, S3 lifecycle policies, and Spot/Savings Plans. I build workflow automation using n8n to connect Slack, Twilio, GitHub, and internal APIs, and I bring strong DevSecOps practices with IAM RBAC, HashiCorp Vault, and incident response ownership.
