Summary
🤩
Rockstar🎓
Top SchoolStefano Borrelli is a Principal Solutions Engineer with 13 years of experience building API-driven, cloud-native infrastructure and control planes. He blends hands-on backend systems work with infrastructure automation, contributing to prominent open-source projects like Crossplane and its AWS providers where he implemented features from CloudFront and service discovery to DynamoDB and Elasticache multi-AZ support. As founder of Asteris and now at Upbound, he bridges product strategy and low-level implementation, with a strong background in storage, clustering, and HPC from earlier roles at Savvis and Citi. Comfortable across languages and environments, he’s equally at home writing controller checksums and checksum algorithms as he is designing systemd and container networking for distributed platforms. Notably, his work often focuses on pragmatic enhancements—like moving operation metadata to annotations and adding IAM AssumeRole tag support—that improve operability at scale.
