• Build and maintain a multi-tenant Kubernetes platform (Azure AKS) hosting applications across multiple development teams. • Architect GitOps deployment workflows (ArgoCD + Helm) and a library of reusable Helm charts standardizing deployment patterns platform wide. • Productionize an internal AI platform: self-hosted Langfuse on Kubernetes (Azure Blob, Valkey, Postgres, ClickHouse) for observability and prompt management of agentic applications. • Deploy and operate a fleet of MCP servers and self-host n8n as the internal workflow automation platform with a vector database (pgvector). • Design and build an event-driven solution to automatically execute SQL scripts on databases hosted in Kubernetes clusters. • Implement scale-to-zero for non-production environments using KEDA, reducing idle compute overhead. • Develop Python tooling for platform components: ClamAV-based antivirus scanning, Langfuse data lifecycle management, and event-driven blob sync between Azure Storage Accounts (KEDA). • Work cross-functionally with Architecture, Security, and development teams to drive cloud-native adoption and upskill DevOps engineers. Stack: Azure, AKS, ArgoCD, Helm, KEDA, Istio, Kyverno, ExternalSecrets, Langfuse, MCP, n8n, PostgreSQL, pgvector, Elasticsearch, Prometheus, Grafana, Python, Golang, GitLab, GitHub

• Externalize data services from Kubernetes to managed CloudSQL instances (GCP), including migration from MySQL Kubernetes services. • Develop Cloud Functions to dynamically provision CloudSQL instances, databases, users, and credentials. • Manage Kubernetes applications using ArgoCD and Helm. • Build Datadog dashboards for platform-wide observability. • Automate Datadog platform configuration using Terraform. Stack: GCP, GKE, Cloud Functions, ArgoCD, Helm, Terraform, CircleCI, Datadog, Elasticsearch, CloudSQL, GitHub, NodeJS

• Design and deploy Kubernetes clusters across environments on AWS (EKS). • Create and maintain Terraform modules for AWS infrastructure (IaC). • Build Helm charts for microservices; collaborate with development teams on Kubernetes configuration and testing. • Set up monitoring and alerting for Kubernetes clusters (Prometheus, Grafana, Alert Manager, PagerDuty). • Build a Python service to export Kubernetes TLS certificates to AWS Certificate Manager. • Automate instance configuration using Ansible; build CI/CD pipelines for Kubernetes services. • Analyze cloud costs and implement optimization measures.

• L3 support on production systems; incident resolution and environment maintenance. • Migrate applications to Tomcat servers: environment provisioning (VMware). • Configuration / integration of external service providers. • Lead evaluation and deployment of a SAN storage solution across production datacenters (Pure Storage, Brocade FC). • Automate operational tasks using Terraform, Puppet, and Jenkins. Stack: Linux (RHEL, Debian), VMware, Terraform, Puppet, Jenkins, GitLab CI, Zabbix, Grafana, Pure Storage, IBM MQ, RabbitMQ, Apache, Tomcat

• Set up and configure CICS transactional environments on Linux (IBM TXSeries on RHEL). • Develop tooling for automated CICS configuration generation (Java, Python). • Performance testing and system tuning for production environments. • L3 support for development teams; technical solution design and documentation. Stack: Linux (RHEL, Debian), VMware, IBM MQ, DB2, Java, Python, Git, JIRA
