Ezequiel Cuellar-Ojeda enhanced Hadoop cluster management workflows in the pentaho/big-data-plugin and pentaho/pentaho-platform repositories, focusing on both user experience and security. He delivered UI improvements for the Hadoop Cluster Import Wizard, unifying dialog titles, adding input validation, and streamlining navigation to reduce onboarding friction. On the backend, he strengthened credential handling by decrypting stored passwords before display and ensuring secure processing of legacy gateway URLs. Ezequiel also enabled full cluster lifecycle management directly from the PDI interface, integrating Java and Pentaho Data Integration (PDI) skills to support centralized, efficient operations. His work demonstrated depth in both frontend and backend development.
