As the Drupal Back-end Developer on the team, I supported CPFL Energia’s web platform, one of Brazil’s largest energy distribution and generation groups, built on a coupled, multisite Drupal 9 architecture running on Acquia’s cloud infrastructure.

I centered my work on back-end engineering, building and maintaining custom modules to enable integrations between CPFL’s internal systems and external APIs, ensuring reliable data flow across a complex multisite environment for a critical infrastructure client.

This included writing custom API endpoints and consumers to exchange data with external systems, and debugging integration issues to keep data consistent across CPFL’s platforms.

I also worked with CI/CD pipelines on Acquia Cloud to automate builds, testing, and deployments across environments, keeping releases consistent across the multisite setup.
