PROFILE

Joshua Duffney

Worked on the microsoft/wassette and bytecodealliance/sample-wasi-http-rust repositories, delivering secure, automated CI/CD pipelines and improving cross-platform release workflows. Integrated keyless artifact signing using cosign, enhanced security auditing with cargo-audit, and streamlined release management through GitHub Actions. Developed onboarding documentation, installer scripts, and dynamic build configurations to support ARM64 and Windows targets, reducing onboarding time and increasing build reliability. Added dependency metadata support and serialization in Rust-based wasm-tools, enabling auditable, compressed module metadata. Used Rust, Bash, and YAML to automate packaging, versioning, and artifact publishing, ensuring reproducible, traceable releases and more maintainable, scalable build systems.
