BA Computer TechnologyAbout me
Platform & DevOps engineer, 15+ years in infrastructure, specializing in large-scale multi-tenant Kubernetes. I manage cluster fleets with GitOps, extend K8s with Crossplane and Kyverno, run observability with Prometheus, and cut cloud cost with OpenCost and Karpenter across AWS, Azure, and GCP.

Cloud Platforms & Infrastructure as Code
Expertise in designing and operating scalable cloud-native and hybrid infrastructure across AWS, Azure, and Google Cloud. Proficiency in Infrastructure as Code tools including Terraform, Pulumi, Crossplane, and AWS CloudFormation, enabling automated provisioning and lifecycle management.
Containerization & Kubernetes Orchestration
Deep experience designing and operating large-scale, multi-tenant Kubernetes platforms across EKS, AKS, GKE, and KubeSpray. Managed cluster fleets of 300+ clusters using Cluster API and GitOps (ArgoCD), and led the evolution from single-tenant to shared multi-tenant architecture. Built custom Kubernetes operators and controllers, and enabled self-service cloud provisioning through Crossplane.
CI/CD Pipelines & DevSecOps
Extensive experience implementing and transforming CI/CD pipelines using Argo Workflows, GitHub Actions, GitLab, Azure DevOps, and Jenkins. Integration of security into platform and CI/CD workflows, embedding automated controls, policy enforcement, and compliance checks across infrastructure and Kubernetes environments.
Monitoring & Observability
Design and implementation of fleet-wide monitoring, logging, and cost-visibility solutions using Prometheus, Grafana, Thanos, Cortex, ELK, and OpenCost. Development of custom Prometheus exporters and advanced monitoring to improve system visibility and incident response.
Cloud Cost Optimization
Per-tenant cost attribution and right-sizing across Kubernetes fleets using OpenCost and Karpenter, driving measurable reduction in cloud spend.
Policy & Governance Enforcement
Implementation of policy-as-code using Kyverno to enforce security, compliance, and governance standards across Kubernetes clusters, ensuring consistent and auditable infrastructure behavior.
Deployment Strategies
Execution of Blue/Green and Canary deployment strategies to minimize downtime. Creation of reusable Helm charts and extension of open-source tooling to standardize deployments and streamline platform operations.
Serverless & Automation
Automation of operational tasks using AWS Lambda and Python. Development of Python solutions for configuring and updating cloud and CI/CD services, reducing manual overhead.
Programming & Scripting Languages
Proficiency in Python, Groovy, Bash, and Go for scripting, automation, and platform engineering workflows.
Configuration Management
Hands-on experience with Ansible for managing infrastructure configuration across diverse environments.
Technical Leadership & Mentorship
Architectural guidance, mentoring, and peer reviews promoting best practices in platform engineering, automation, and security. Leadership of cross-functional DevOps and Platform Engineering teams.

Project history
Architected and implemented complex cloud-native infrastructure solutions with a focus on High Availability, Disaster Recovery, and Cross-Region architectures. Led the transition from single-tenant to multi-tenant Kubernetes platforms, managed large-scale Kubernetes cluster fleets using Cluster API and GitOps (ArgoCD), drove CI/CD transformation from GitLab CI to Argo Workflows, led adoption of declarative IaC using Terraform, Pulumi, Crossplane, and Azure Service Operator, built custom Kubernetes operators and controllers, implemented policy-as-code using Kyverno, integrated DevSecOps practices, designed observability solutions using Cortex, Prometheus, ELK, and OpenCost, developed custom Prometheus exporters, created reusable Helm charts, and provided technical leadership and mentorship.
Planned, organized, and implemented DevOps and SRE practices across multiple projects. Designed and developed IaC solutions for AWS, Azure, and bare-metal setups. Worked with Kubernetes solutions including AKS, EKS, and KubeSpray. Implemented CI/CD infrastructure using Jenkins, JCasC, pipelines, and shared libraries. Executed Blue/Green and Canary deployment strategies. Established monitoring, alerting, and log collection frameworks using Prometheus and Grafana. Collaborated with development teams on ML/AI platform using Docker and Kubernetes. Developed Python solutions for Azure DevOps automation.
Organized team members and supported the Acronis Backup Cloud platform. Maintained platform availability and introduced virtual infrastructure provisioning for on-premise data centers. Implemented Continuous Delivery with Jenkins, developed Jenkins jobs as code using Groovy, DSL, and Simple Templating Engine, created Jenkins Shared Libraries, maintained multiple on-premise Kubernetes clusters, improved monitoring with Prometheus exporters and Grafana dashboards, and automated numerous manual processes.
