What I'm looking for

I'm looking to build secure, scalable cloud-native platforms in a collaborative startup or cross-functional environment, improving CI/CD automation, Kubernetes operations, infrastructure as code, security compliance, and reliability.

At Human Managed, I build and secure CI/CD workflows for cloud-native microservices, integrating SAST, DAST, IaC scanning, Snyk, and GitLab security scans. My vulnerability-management process reduced vulnerabilities by 80%.

I lead GitLab self-managed-to-SaaS migrations, container registry migrations, and GKE runner integration while contributing to ArgoCD automation and Kubernetes upgrades across GKE and EKS. I also automate AWS infrastructure through GitLab CI/CD, Crossplane, GitOps, and infrastructure as code.

Previously at PearlThoughts, I delivered DevOps infrastructure across six real-time projects, including hellomainland.com and its associated platforms. I built CI/CD infrastructure that reduced deployment time and scalability effort by 70% while improving team productivity by 45%.

I enjoy startup environments where I can improve platform reliability, security compliance, deployment automation, monitoring, and incident response. I also build Docker-packaged Airbyte connectors, Helm-based application deployments, and personal SaaS and mobile projects.
