Rockstar🎓
Top SchoolCalin Don is a pragmatic, language-agnostic engineering leader and co-founder with 13 years of experience building cloud-native and web platforms from Romania. As Co-Founder & CTO at Bitpoke and previously co-founder/CTO of Presslabs, he blends hands-on backend development with product-level ownership, shipping infrastructure and SaaS features. His open-source contributions show deep systems chops—improving Kubernetes controller-runtime reliability and enhancing versioned filesystem and MySQL orchestration tooling—highlighting a focus on resilient, containerized deployments. A perfectionist and lifelong WordPress tinkerer since 2005, he pairs a service-oriented mindset with careful attention to logging, error handling and operational edge cases. He is equally comfortable writing low-level fixes (statfs, symlink support, `.gitignore` parsing) and designing Docker-friendly deployment flows. Based in Timiș, he brings entrepreneurial grit, deep DevOps/database experience, and a bias for shipping robust, observable systems.
