Rockstar🎓
Top SchoolJonathan Goldwasser is a Brussels-based manager and technologist with a decade of professional experience and an MSc in Electrical Engineering from Université libre de Bruxelles. He leads Goldwasser Exchange while contributing hands-on to major open-source cloud projects—implementing build and configuration features in projen, improving S3/ECS and CI Docker caching in aws-cdk, and hardening device and session handling in amazon-cognito-identity-js. His earlier career in project management and business development for large energy firms (Electrabel/GDF SUEZ) gives him a rare blend of operational rigor and cloud-native engineering judgment. Equally comfortable writing TypeScript unit tests and specifying infrastructure policies, he focuses on making developer workflows and production deployments more reliable and secure. He frequently applies systems-level thinking from power-plant feasibility studies to cloud architecture and CI tooling, helping teams bridge business requirements with practical, auditable implementations.
