I'm a Senior DevOps Engineer and Cloud Architect with 15 years in software and infrastructure — the last decade designing and operating secure, cloud-native platforms for FinTech, Healthcare, and E-commerce clients at Deloitte and DataArt.
Core expertise:
- Kubernetes & cloud-native: production clusters on EKS, GKE, AKS, and OpenShift with Helm, Kustomize, ArgoCD, and FluxCD.
- Multi-cloud & Infrastructure as Code: reproducible infrastructure on AWS, GCP, and Azure using Terraform, Terragrunt, and Ansible; AWS Organizations and Control Tower for multi-account governance.
- CI/CD & GitOps: end-to-end automated delivery with GitHub Actions, GitLab CI, Jenkins, and the AWS Code* suite.
- SRE & observability: Prometheus, Grafana, Loki, ELK, and Datadog; on-call experience keeping high-load systems at 99.9% uptime.
- Security & compliance: leading infrastructure for PCI DSS Level 1, HIPAA, FDA, and GDPR environments, with automated SAST/DAST scanning (Fortify, SonarQube, Blackduck) and policy enforcement (OPA, Vault).
Selected results:
- Cut deployment failures by 80% by redesigning CI/CD with the AWS Code* suite.
- Reduced mean time to recovery by over 50% with a Prometheus-based monitoring stack.
- Lowered operational costs by 27% (Fargate migration) and 55% (serverless/Lambda migration).
- Led PCI DSS Level 1 compliance from the infrastructure side for a global payment gateway handling millions of transactions per day.
I've delivered at scale — including infrastructure monitoring 1,000,000+ healthcare devices across US hospitals and the hospitality platform for major international sporting events. Programming in Python (expert), Bash, and Go. PhD in Computer Science (Cybersecurity), fluent English (IELTS C2). Available fully remote for long-term and project-based work.
