Google-Grade Reliability for Your Cloud Infrastructure. GCP 10x Certified, AWS 1x Certified, Databricks 1X certified
Senior Infrastructure Architect and former Google SRE (11 years) and Oracle Engineer with over 25 years of experience managing global-scale production environments. If you are looking for a "pair of hands" to write scripts, there are many options. If you are looking for an Owner-Architect to design, secure, and scale your business-critical infrastructure with zero-risk execution, let’s talk.
With 10x GCP Professional Certifications, I specialize in taking complex, high-traffic ecosystems and making them resilient, cost-effective, and simple to manage.
Expertise Across the Stack:
Cloud Architecture: Expert-level design and migration across GCP, AWS, and Hybrid Cloud.
DevOps & SRE: Implementing "True SRE" principles—SLOs, error budgets, and automated toil reduction.
Infrastructure as Code (IaC): Building reproducible, version-controlled environments using Terraform, Helm, Ansible, and Packer.
Kubernetes & Orchestration: Deep experience with GKE, EKS, and self-managed clusters (Rancher).
Security & Compliance: Hardening infrastructure via VPC Service Controls, Zero-Trust IAM, and automated security pipelines.
CI/CD Optimization: Streamlining delivery via Jenkins, GitHub Actions, and Google Cloud Build.
Why Work With Me?
The "Google" Standard: I apply the same rigor and reliability standards I used at Google to your infrastructure, ensuring 99.9% availability.
Cost Efficiency: I specialize in cloud cost optimization, often saving my clients more in monthly cloud spend than the cost of my engagement.
Simplicity at Scale: I believe the best architecture is the simplest one that solves the problem. I build systems that your team can actually maintain.
Technical Proficiencies:
Linux: 20+ years of deep systems-level expertise (RHEL, Debian, Ubuntu).
Automation: Puppet, Ansible, Terraform.
CI/CD: Jenkins, Artifactory, GitHub, Cloud Build.
Containers: Docker, Kubernetes, Container Registry.
