Author of Rust Blockchain: A Full-Stack Implementation Guide, a 24-chapter, 696-page book covering Axum, Iced, Tauri 2, Tokio, SQLCipher, Docker, and Kubernetes through one cohesive project. I write about building real systems in Rust — from blockchain infrastructure to desktop applications. Currently exploring the move from JVM-heavy data platforms to a Rust-native Big Data stack as a path to 10x more efficient data pipelines, eliminate GC pauses and reduce infrastructure costs using Arrow and DataFusion.
