Worked on enhancing WebAssembly support in the fyne-io/tools repository by removing CGO dependencies to enable pure Go builds for WASM targets. Focused on backend development and testing, the approach involved setting CGO_ENABLED=0 in both build and test environments, ensuring deterministic and portable builds across platforms. This change reduced reliance on C bridges, minimized the C dependency surface, and improved the reliability and reproducibility of continuous integration workflows. By applying these adjustments consistently in CI and build scripts, the work facilitated more robust cross-platform deployment readiness. The primary technologies used included Go, backend automation, and automated testing practices.
