• Architect, built and deployed a large scale Elastic Stack cluster at Optum/UHG.• Maintain an Elastic Cluster supporting 500+ application teams, monitoring 10,000+ micro-services,a scalable architecture with an ingest of 300,000+ events per second over 1500+ data streams, persisting over 250 TB of metric, trace & log data.• Upgraded 2 Major Elastic releases(6x -> 7x -> 8x) with no outage, migrated prod cluster from k8s to linux vm's with no outage, upgraded over 16 minor releases across 4+ clusters with no outage. • The 8x Elastic Cluster has full observability capabilities including kibana, apm-server, logstash, elasticsearch, SLO, (data ingest, master, machine learning). Cluster usage primarily application performance monitoring (APM)• Automated Elastic Cluster operations with Jenkins, include deploy, upgrade and service actions usingAnsible, Docker, Kubernetes and Nomad.• Elastic Cluster setup to ingest OpenTelemetry (OTEL) Agents & Collectors.• Dev/Test Elastic clusters ECK & yaml built on Google Cloud (GCP), Azure and AWS using Kubernetes, Artifact Registries, Docker and Containerization, with elastic data storage tiers.• Generated a Java Spring Boot Rest API interface to create a kibana space environment via API or Swagger unique to each app teams data and views at on-boarding time.• Using Active Directory groups and Kibana spaces each app team, is given a personalized view where they will see only their data. Next each app team can add other app teams data to their view as needed.• The cluster is resilient Elastic Stack Cluster presently having an uptime of 5+ years.• Created a Java Spring Boot Canary App leveraging Jmeter, with Jenkins, CI/CD, to send traffic to all data centers guaranteeing absolute availability and alerts on ingest outages.• Maintain an Elastic Stack monitoring cluster to triage prod systems

• Onboarded numerous applications teams to Dynatrace Appmon and Dynatrace platforms. • Created reference example deployments patterns for Dynatrace Appmon & OneAgent ( Java, Nodejs, .NET, Go) running on (VM's (Linux/Windows), pods/containers (k8s, nomad, openshift))• Proof of Concept evaluation open source and low cost Observability tools as replacement for Dyntrace (InspectIT, Prometheus, Open Telemetry, Elastic )• Created deployment yamls for entire elastic stack cluster on k8s before ECK existed.
