We have optimized Docker image layer caching and CI performance:

Updated the Dockerfile to use lukemathwalker/cargo-chef for separating external cargo dependency compilation from application source compilations.
Modified .github/workflows/backend-ci.yml to utilize Docker Buildx and docker/build-push-action@v6 with GHA caching (cache-from: type=gha and cache-to: type=gha,mode=max).
Integrated swatinem/rust-cache@v2 across lint-check-type and test jobs for robust Rust compilation caches.
Updated documentation in README.md explaining the caching architecture and pipeline optimizations.
Closes #137

google-labs-jules Bot and others added 2 commits July 17, 2026 13:04
- Multi-stage Docker build utilizing `cargo-chef`
- GitHub Actions Buildx integration using `type=gha`
- Upgraded Rust caching to `swatinem/rust-cache@v2`
- Documented cache design and benefits in README.md
