▪ Designed a framework for the complete automation of Talend upgrades.

During this project, I developed a comprehensive framework for automated Talend version upgrades. I utilized Talend MetaServlet APIs for Talend Administration Center and the Talend CommandLine. I also implemented GIT for branch and tag management, enabling simultaneous use of two code versions (Old Talend code vs. New Talend code), along with MAVEN and Nexus for managing artifacts, dependencies, and custom components.

As part of this project, I also managed the installation of Talend Job Server and Talend Runtime using Ansible for automated deployment. Furthermore, I migrated users, roles, tasks, triggers, and contexts from the Talend Administration Center.

The installation was part of the project's infrastructure component, involving the administration of several servers for different environments.
