PROFILE

Mario Winkler

Worked on modernizing and securing the Registration Harvester deployment for EOEPCA, delivering features across the eoepca-plus and helm-charts-dev repositories. Focused on Helm chart versioning, configuration management, and secret handling, the work replaced hardcoded credentials with Kubernetes Secrets and introduced sealed secrets for IAM authentication. Used YAML and shell scripting to standardize deployment workflows, improve traceability, and enable dynamic, environment-specific configurations. Enhanced CI/CD pipelines and streamlined release engineering by aligning chart versions and image tags, supporting reliable upgrades and rollback. These efforts improved deployment reliability, security, and operational visibility, reducing manual intervention and accelerating feedback for new feature validation.
