- Engineering and Architecture team providing expert support for Virtualization, Kubernetes, Storage, GenAI, and Infrastructure as Code (IaC) initiatives. We handle high-priority, complex projects and work directly with Line of Business (LOB) and engineering teams to design innovative solutions.- Engineered a multi-architecture GenAI Platform, enabling developers to use LLMs like LLaMA for tasks such as classification, sentiment analysis, and text generation. This open-source, multi-architecture platform supports Nvidia and AMD accelerators, leveraging Kubernetes with run.aifor GPU management.- Designed a GitOps-based Kubernetes platform, enabling developers to dynamically provision and deploy applications within their own clusters. This offering accelerates the transition from legacy VMs by allowing developers to containerize and modernize their apps on a fit for purpose platform. The GitOps workflow uses ArgoCD for customizing operators and Helm charts, providing full self-service with CD tools like Harness to manage namespaces.- Successfully implemented RHEL in-place upgrades, automating the migration from RHEL 7 to 8 using Leapp and Ansible Automation Platform. The process included creating backups, upgrading the OS, and managing post-provisioning integrations and layered product upgrades. Within 6 months, scaled to ~1,500 upgrades per month, with plans to reach 3,000-4,000 per month.- Kubernetes Engineering (OpenShift)- GenAI Platform Engineering (Nvidia, AMD, run.ai)- Platform Automation (Ansible)- High Performance/Low Latency Compute- Azure/GCP IaaS Enablement- OS Engineering (RHEL, Windows, Unix)- Virtualization Engineering (VMware/Nutanix)

Lead Citi’s Platform and Automation Engineering teams, promoting an open culture and empowering teams to share, reuse, and solve problems through automation.- Evaluated and introduced new technologies to accelerate Citi's Infrastructure as Code (IaC) transformation from proof of concept to production. Successfully implemented tools such as Ansible Tower, HashiCorp Vault, Terraform, Packer, OpenShift (Kubernetes), Knative, and Tekton, driving automation and operational efficiency.- Automate Everything: Transform business logic into code. Disband centralized automation teams and equip teams with the right tools to build their own automation. Foster a culture of managing infrastructure through code and creating a common framework where all actions are driven APIs (Ansible, Chef, Terraform). - Modernize Our Apps: Rapidly prototype and migrate applications to container and container orchestration platforms (Kubernetes).- Public Cloud: Develop pipelines that enable applications to seamlessly move between providers, leveraging public cloud for hosting and burst capacity (AWS, GCP).- CI/CD Pipelines: Automate the build, test, and release processes of code through CI/CD pipelines integrated with all configuration management tools (Jenkins, BitBucket, Artifactory).- Monitoring, Aggregation, Analytics: Collect, organize, and present data in a user-friendly manner. Empower end users to create their own visualization layers and easily connect data points. Integrate this data into automation frameworks to enable automated remediation and self-healing infrastructure (Splunk, ELK, AppDynamics, Sensu).
