Worked on security-focused enhancements across the grafana/grafana and prowler-cloud/prowler repositories, delivering targeted improvements in documentation and configuration management. In grafana/grafana, contributed detailed Markdown documentation guiding operators to enable Basic Authentication for Grafana metrics, reducing information leakage and aligning deployments with security best practices. In prowler-cloud/prowler, implemented the deprecation of SHA-1 for AWS ACM certificates by updating YAML configuration files and Python scripts, ensuring compliance with modern cryptographic standards. Leveraged skills in AWS, cloud security, and documentation to address security risks, focusing on operator guidance and automated checks rather than direct code changes, resulting in safer, more compliant environments.
