I am a Principal-level DevOps, Platform, and Cloud Architecture professional with 15+ years of experience building and modernizing production infrastructure across AWS, Kubernetes, Linux, CI/CD, and Infrastructure as Code ecosystems. My work sits at the intersection of platform engineering, cloud architecture, DevOps, SRE, observability, security, compliance, and engineering enablement. Over the years, I have led initiatives spanning AWS migration, Kubernetes platform modernization, GitOps adoption, Infrastructure as Code transformation, observability redesign, disaster recovery planning, cloud cost optimization, and PCI-DSS-aligned infrastructure improvements. Across my career, I have focused on building platforms, not just pipelines — creating reusable cloud and delivery patterns, improving reliability through engineering standards, strengthening auditability and operational visibility, reducing complexity for engineering teams, and aligning platform decisions with business goals such as speed, resilience, governance, security, and cost efficiency. Highlights of my experience include: • reducing AWS observability costs by 60% through Prometheus, Grafana, and Loki-based redesign • reducing cloud spend by 50% through AWS EKS optimization, autoscaling, and cloud-native platform improvements • reducing deployment time to under 3 minutes through GitOps-driven delivery and CI/CD standardization • leading Kubernetes and microservices modernization initiatives, including migration of 20+ services to AWS and Kubernetes platforms • leading migration of 3,000+ Linux servers to AWS in 6 months • driving Infrastructure as Code transformation using Terraform and Terragrunt across AWS environments • refactoring cloud infrastructure to support PCI-DSS compliance objectives and stronger governance controls • delivering 99.9% availability across critical environments through resilient architecture, automation, and disaster recovery planning Technically, I work across AWS, Kubernetes, Terraform, Terragrunt, GitLab CI, GitHub Actions, Jenkins, Argo CD, Flux CD, Helm, Prometheus, Grafana, Loki, Datadog, SonarQube, and DevSecOps-oriented tooling. I am especially interested in Principal, Staff, Architect, and Platform leadership roles focused on cloud strategy, platform architecture, Kubernetes modernization, AWS governance, Infrastructure as Code transformation, observability, compliance, and engineering effectiveness at scale.
Leading infrastructure standardization and cloud governance initiatives across AWS environments with a strong focus on Infrastructure as Code, security, and compliance. • Architected and implemented the company’s Infrastructure as Code foundation using Terraform and Terragrunt, turning AWS environments into scalable, reusable, and governed platforms. • Led the transformation of existing AWS infrastructure into fully codified, IaC-managed environments, improving consistency, auditability, and operational resilience. • Refactored infrastructure to support PCI-DSS compliance objectives, strengthening security controls, audit readiness, secrets governance, and controlled delivery practices. • Designed reusable Terraform modules and environment structures to reduce configuration drift and improve long-term maintainability. • Contributed to platform architecture decisions across AWS governance, compliance, standardization, and cloud reliability. Key technologies: AWS, Terraform, Terragrunt, IAM, AWS KMS, AWS Secrets Manager, CloudTrail, PCI-DSS, Docker, Kubernetes, Helm, ECR, Argo CD
Worked on platform architecture, observability, DevSecOps, and cloud efficiency initiatives in a highly regulated environment. • Led the architecture and implementation of enterprise observability and telemetry capabilities using Datadog, with focus on auditability, production visibility, and engineering accountability. • Drove AWS cost optimization and platform efficiency initiatives aligned with KPI-based FinOps goals. • Designed and implemented SonarQube-based static analysis capabilities to strengthen software governance and DevSecOps maturity. • Architected self-service platform capabilities for deployment, monitoring, and engineering enablement. • Contributed to platform strategy across reliability, governance, security, and delivery standardization. Key technologies: AWS, Datadog, SonarQube, DevSecOps, FinOps, Platform Engineering
Focused on AWS platform modernization, Kubernetes adoption, GitOps, and observability transformation. • Architected AWS-based platform services for production workloads by combining Kubernetes, GitOps, observability, and automation into a reusable operating model. • Reduced AWS observability costs by 60% through redesign of the monitoring and logging stack using Prometheus, Grafana, and Loki. • Improved deployment safety, consistency, and traceability by implementing Argo CD-based GitOps delivery. • Led the migration of a Ruby on Rails application from EC2 to Kubernetes, improving resilience, self-healing behavior, and deployment consistency. • Built reusable GitLab CI components and Helm-based delivery standards to improve standardization across teams. Key technologies: AWS, Kubernetes, Argo CD, GitLab CI, Helm, Prometheus, Grafana, Loki
Worked on cloud-native platforms, AWS EKS, GitOps, autoscaling, and Kubernetes-based modernization initiatives. • Designed and operated AWS EKS platforms for microservices workloads with emphasis on scalability, resilience, and delivery speed. • Reduced cloud spend by 50% through autoscaling, auto-healing, and cloud-native optimization strategies. • Achieved 99.9% uptime and reduced deployment time to under 3 minutes through GitOps-based delivery using Flux v2 and Argo. • Architected dynamic CI/CD capabilities that automatically provisioned isolated staging environments from merge requests. • Converted AWS infrastructure into Terraform-managed foundations and improved monitoring through Prometheus Operator. • Designed secure Azure AKS environments with hybrid connectivity between cloud and on-premises systems. Key technologies: AWS EKS, Azure AKS, Terraform, Flux CD, Argo, Prometheus, Kubernetes, CI/CD
Contributed to large-scale application modernization and cloud-native platform transformation initiatives. • Led modernization of application infrastructure from monolithic delivery patterns into AWS EKS and serverless-aligned architectures supporting 20+ microservices. • Delivered approximately 60% annual savings through platform modernization and cloud-native operating improvements. • Sustained 99.9% availability through resilient container orchestration, automated delivery, and proactive operational controls. • Implemented Infrastructure as Code with Terraform, reducing deployment and rollback times to under 10 minutes. • Established proactive observability capabilities using Datadog, New Relic, and PagerDuty. • Optimized Elasticsearch environments to improve stability, performance, and recovery readiness.
