June 2025 monthly summary focusing on key accomplishments and business value across two repos. Key features delivered include cross‑platform WASM tooling, playground deployment, and related CI workflows in Hakana; a frontend UI refresh for better mobile/tablet responsiveness; expanded docs around Hakana playground; and important internal improvements to the type system and static analysis. In parallel, TypeScript-Go benefited from design-level improvements to type inference in destructured defaults. Overall impact: accelerated development and deployment of a cross-platform WebAssembly playground, improved user experience and documentation, cleaner internal data structures, and higher quality code with stronger static analysis. This supports faster iteration, lower maintenance cost, and broader platform coverage for Hakana, while lifting code quality in the TypeScript-Go refactor work. Technologies/skills demonstrated: GitHub Actions CI for WASM builds and playground deployment; macOS WASM support and conditional compilation; CSS/UI polishing and responsive design; docs overhaul; internal type system cleanup; static analysis improvements; and type-inference optimization in TypeScript-Go.
