Assist in different PaaS and IaaC while utilizing complete automation by configuringdifferent platforms as a service like Argo-cd, Rancher-fleet or Suse; RKE2, RKE1,K3s, RHEL clusters OpenShift, observability stack with ELK Stack, security andcompliance with scanning tools like Kyverno, Gatekeeper, SealSecrets, Vault.Orchestrate, implement and maintain public cloud resources about KubernetesAzure AKS and AWS EKS. Integrate automation scheme, CICD pipeline likeGitLab/ci, GitHub/action for orchestration, provision and deployment of Terraformmodules, Azure Container Registries(ACR), application helmcharts, kustomizationmanifest in an Azure/AKS environments. Provision production grade GKE clusterswith IaC such as Terraform and configure Apigee on GKE clusters with APIsgateway applicants deployed to enforce security and networking policies. IntegratedDataproc on GKE clusters. Responsible for numerous cluster upgrades and clusterperformance. Helped build CRDs(Custom Resource Definition) using programminglanguages like Goland or Python to optimize Kubernetes clusters operation. SomeCRD controllers involve developing/implementing controllers like Whisper, whichoperates like seal-secret or external-secret but with the difference in that sense thatthe secrets are stored in an external database like CansandraDB are exported as asidecar to respective deployments that need them, and they are encrypted at rest.

Full Stack Kubernetes deployment, architecture, provisioning, and orchestration on AWS, Azure, GCP and Rancher airgap/on-premise as well as Openshift environments. Responsible for cluster maintenance; upgrade and patching. Provisioning of various Kubernetes flavors (EKS, RKE2, AKS, GKE, EKS, OC, Tanzu) clusters for various teams and business environments needs. Orchestrate various Kubernetes flavors (EKS, RKE2, AKS, EKS, OC, Tanzu) with infrastructure as code like Terraform, Ansible, etc for different needs as require. Configure the required CICD pipeline for developers. Provide assistance to developers on how to deploy built artifacts or applications into clusters using helm pass as environment variables defined in a jenkinsfile. Helm package enterprise application with helm/helmcharts and secure various chart artifacts. Used various K8s orchestrators to provision K8s on AWS; rancher, kops, eksctl, and launch template scripts.

Full Stack Kubernetes platform management and orchestration with infrastructure as code with Terraform. Helped migrate on-prem Tanzu cluster environment to cloud like Azure/AKS. Configure all variety of observability/monitoring required based on environment needs; setup Prometheus, Grafana, alertmanager for cluster scope monitoring and application resource management. ELK Stack Elasticsearch, fluentd, Logstash for application logs monitoring and management. Use Terraform to manage keycloak realm access policy. Helped configure different CD integration for AKS and Tanzu clusters; setup source repo with ArgoCD and fluxCD with Kustomization for all available cluster. Manages cluster upgrade/patching and application secrets with Sealsecret.

Technical lead and principal architect working with AWS EKS on apple proprietorial tools like Rubix and whisper. Implementing highly available K8sclusters on the cloud (AWS) and using Rubix and Denali for some network configuration and network security. Worked on various areas; Databases, Networking, Rolling Updates, Istio, Security, Logging Monitoring, and Tracing. Used Apigee for API monitoring and security and configure Whisper for secrets and configmap in Kubernetes. Whisper avoids the need of having to create secrets and configmaps in your cluster. It provides the app's confidential data as a sidecar andinjects them at runtime into the respective apps.

Assist in deploying Kubernetes into air-gapped enterprise environments with kops self-hosted assets. Implemented the capability to re-use security groups, and IAM profiles in order to pass security review and PEM testing. Utilized helm charts to deploy Cassandra and Datastax enterprise. Designed and implemented Cassandra containers and stateful sets based on contributed Kubernetes Cassandraexamples.Implemented POC using weave to create a mesh pod network between K8s clusters. Mentored developers in K8s design and custom application implementation.Assist in orchestrating OpenShift on Airgap, On-premise clusters iDRAC Dell power servers. Helped administer, and provision data lab tools such as Domino which is used for Data Science analytics. Manage and maintain Data scientists requesting workspace on the platform and enabling of data tools such as Hadoop, Python, etc. Administer RBAC with Okta and AD on the platform.Add/configure and enable NVidia GPU capability to new or existing clusters for optimization based on MLOps or AI deployments to clusters. This was done by configuring Nvidia operators/CRD and NodeDiscovery which helps the cluster to detect and schedule any MLOps, AI, or GPU deployments to respect nodes with GPU capability.

Lead architecture and deployment of Kubernetes deployment for trebuchet SASplatform hosted in AWS. Architecture included CNI networking and installation tool selection. Designed kops private topology, deploying nodes in private VPC utilizing AWS Nat Gateways. Mentored staff on advanced Kubernetes DevOps, microservices, and stateful applications. Assisted with maintaining 5/9’s availability of Kubernetes environments. Focused on furthering Mantl, Terraform, and vSphere integration. Assisted in setting up vSphere 6.0 test cluster, allowing for end-to-end system tests. Contributed to Terraform project, written in Go, and assisted in managing various bugs on Github. Modified and tested Mantl Ansible python plug-ins allowing for the use of a new terraform provider.

ADT – Expanded functionality of previously implemented Spring based web services. This service layer provided the custom capability to create forecasts of future tasks within a running Savvion BusinessManager process. Mentored staff in utilizing Spring based JUnit testing to save considerable time testing functionality outside ofthe Savvion container. Garden City Group – Assisted with the creation of a custom adapter for the integration of web services. Implemented various examples, including a web application that hosted CXF web services. This application provides examples of how to integrate an external web application with Savvion BusinessManager via the BizLogic Client API. Using an external web application allows the creation of new Savvion components while not adding the custom code to the Savvion installation. This architectureallows for easier future upgrades. Worked with GCG to create production architecture for SBM 7.8 deployed on RedHat JBoss AS.
