WORK HISTORY
Enterprise Devops Engineer @Elekta
London, GB
Designed, implemented and evolved secure CI/CD platforms using Azure DevOps & GitHub Actions for Windows servers, Azure AKS and on-prem K8s across multiple products. Provisioned and managed production-grade AKS/on-prem K8s with Terraform/Packer (node pools, private networking, ingress, Azure Policy, automated upgrades). Built secure container supply chain: hardened images, Trivy/Veracode/Nessus scans, signed artifacts, pushed to ACR achieving zero high/critical vulns in prod. Automated wildcard TLS cert rotation via Azure Key Vault + Functions, removing manual renewals and cert incidents across ingress controllers. Maintained/updated self-hosted Azure DevOps agents with Terraform/Packer and latest secure OS/tooling. Integrated security & quality gates in CI/CD: SonarQube, Trivy, Veracode, Nessus, OWASP ZAP/DAST for polyglot stacks. Hardened K8s to CIS: RBAC/least privilege, network policies, audit logs, Pod Security Standards, immutable containers, OPA/Gatekeeper. Implemented GitOps with ArgoCD for declarative, auditable rollouts/rollbacks in production K8s. Built observability with Prometheus, Grafana, EFK/ELK, Azure Monitor, tracing to enable SLO/SLI tracking and proactive incident response. Led Azure FinOps (rightsizing, RIs/Savings Plans, auto-shutdowns, budget alerts) delivering ~50% monthly cost savings. Optimized pipelines via caching, parallelism and stage pruning, reducing durations by 60–75%. Acted as key interface between dev, QA, security and ops to troubleshoot releases and improve delivery quality.

ABOUT NARENDRA JANNE
Enterprise DevOps & Cloud Infrastructure Engineer (SRE) with 9 + years (Azure-first, AWS experience) delivering secure, scalable platforms. Led an org-wide Azure FinOps program achieving ~50% monthly cost reduction; strengthened supply-chain security with OCI image signing (Notation/Notary v2); codified landing zones and application stacks with Terraform; and built end-to-end CI/CD via reusable Azure DevOps templates and GitHub Actions adopted across multiple business lines. Deliver Kubernetes workloads on Windows & Linux with strong governance (Azure Policy/RBAC/Key Vault) and SLO-driven observability. In parallel, built and deployed on AWS a suite of LLM agents using Llama 3, Mistral, and DeepSeek-R1 for ATS resume generation, role-specific interview preparation and mock-interview scheduling, web-wide job aggregation, and a privacy-aware foundation shade matcher.CI/CD & Release : Azure DevOps Pipelines (YAML, Environments/Approvals, Templates), GitHub Actions, Jenkins; Helm, Argo CD/Flux; blue/green & canary strategiesIaC & Config : Terraform/Terragrunt, Bicep/ARM, Ansible, PackerContainers & Orchestration : Docker, Kubernetes (AKS/EKS), Windows/Linux nodes, Helm, Kustomize, Ingress (NGINX)Observability & Monitoring : Azure Monitor, Log Analytics, Application Insights, Prometheus, Grafana, ELK/OpenSearch, KibanaSecurity & Compliance : Image signing (Notation / OCI Notary v2), ACR content trust, RBAC/PIM, Azure Policy/Blueprints, Key Vault, OPA/Conftest, Defender for Cloud, CIS hardening, SAST/DAST, SBOM (CycloneDX)Networking : Hub-Spoke, Private Link/Private Endpoint, Application Gateway/WAF, Front Door, DNS, VPN/ExpressRouteData & Messaging : Azure SQL, PostgreSQL, Redis, Event Hubs/Kafka, Service Bus, SQS/SNS, RDS/AuroraScripting & OS : PowerShell, Bash, Python; Linux (RHEL/Ubuntu) & Windows ServerCollaboration & Docs : Jira, Confluence; Runbooks, ADRsVersion Control : Git (GitHub/Bitbucket/Azure Repos), SVNBuild Tools : MavenDeployment Tools : Azure DevOps (Pipelines/Environments), AWS CodeDeploy, SpinnakerCloud: AWS (Core Services): EC2, ELB/ALB/NLB, VPC, S3/CloudFront, IAM, RDS, Route 53, CloudWatch/CloudTrail, CodeDeploy, Secrets Manager, Kinesis, SNSCloud: Azure & Azure DevOps : ARM/Bicep, AKS, VNets/NSG, Storage/Blobs/Files, Azure SQL, ACR, Azure Artifacts, Repos, Pipelines, Ingress, Agent Pools, scalability featuresConfiguration Management : AnsibleStream Processing : Apache Kafka, Apache StormProgramming Languages : Java,TypeScript, HTML, CSS, JavaScriptLLM/Agents : Llama 3, Mistral, DeepSeek-R1
