Worked on enhancing the libherokubuildpack component within the heroku/libcnb.rs repository by delivering a secure and reliable file download feature. Migrated the HTTP client from ureq to reqwest and integrated the OS TLS certificate store using rustls-tls-native-roots, enabling support for environments with custom certificate authorities. Improved error handling by ensuring non-success HTTP statuses return a DownloadError, and added targeted tests to cover 404 scenarios. This work, implemented in Rust and focused on buildpacks, error handling, and TLS, increased security, reliability, and deployment flexibility for enterprise users while maintaining a strong emphasis on test-driven development and code quality.
