PROFILE

Alberto Miranda

Worked on nextflow-io/nextflow and seqeralabs/tower-cli, delivering features that enhanced security, reliability, and cross-cloud automation. Built a Fusion Token Validation and Licensing Framework using Java and Groovy, introducing robust token validation, licensing checks, and exception handling to ensure secure, compliant deployments. Improved test resilience by adding exponential backoff and tracing to S3 copy operations with bash scripting. Enhanced tower-cli by enabling single VM compute environment creation across AWS, Azure, and Google Cloud, and streamlined configuration management. Added local file URL support for Fusion container configs, implementing strict URI validation and contextual error reporting to simplify development and troubleshooting.
