Three-Tier-Application

I designed and deployed a 3-tier web application (Frontend, Node.js API, and PostgreSQL database) on a Kubernetes cluster, where the frontend and backend were containerized using Docker and the database was configured with persistent storage. To ensure continuous delivery, I implemented a GitHub Actions CI/CD pipeline that automated Docker image builds, pushed them to Docker Hub, and updated the Kubernetes deployments with rolling updates, enabling seamless and reliable end-to-end application delivery.
