Skills: Kubernetes | Docker | CI/CD | Linux | Azure | Bash | YAML

• Proficient in containerizing applications using Docker and deploying them on Azure with Kubernetes as the orchestration platform.
• Developed and maintained CI/CD pipelines to enable automated deployment workflows, significantly reducing manual efforts.
• Migrated legacy applications on-premise Linux servers to Azure by containerizing using Docker Compose, Kafka, Zookeeper, and Docker Volumes for persistent storage.
• Deployed multiple microservices to Azure using Kubernetes components such as Pods, Services, Deployments, DaemonSets, Ingress Controllers (via Helm), and PersistentVolumes (PV/PVC) through declarative YAML manifests.
• Unified disparate repositories under centralized CI/CD pipelines, leveraging custom Bash scripts for build, test, and release automation, achieving a 100% reduction in manual deployment efforts.
• Designed self-triggering pipelines to proactively manage vulnerabilities in .NET, Node.js, and Docker containers.
• Secured deployments by utilizing Kubernetes Secrets for managing sensitive data like storage credentials, application configurations, and TLS-based DNS secrets.
• Configured ClusterRoleBindings for service accounts to facilitate secure and role-specific deployments across multiple namespaces within the CI/CD pipeline.

Skills: MS SQL | C# | ASP.NET Core | Nginx | Kafka

• Developed convention-based CRUD APIs (GET, POST, PUT, DELETE) using ASP.NET Core, adhering to RESTful principles.
• Optimized SQL stored procedures and dynamic queries using advanced performance tuning techniques to enhance application responsiveness.
• Integrated Apache Kafka and Zookeeper with .NET services to improve system throughput and eliminate deadlocks in message-driven architectures.
• Deployed Nginx within Dockerized environments for efficient DNS routing, enhanced with caching, Content Security Policies (CSPs), custom proxy timeouts, file upload limits, and restriction of insecure HTTP methods.
