Worked on packaging and build-system hardening for the linuxdeepin/dde-shell repository, focusing on improving compatibility and reliability across target distributions. Updated build dependencies and package control files, refined versioning, and adjusted build-depends relationships to streamline the build process. Reorganized file installations and removed unused build flags, simplifying maintenance and reducing potential sources of error. Leveraged skills in Debian packaging, build systems, and packaging best practices, using C++ and Shell scripting to implement these changes. The work laid a foundation for reproducible builds and smoother future releases, addressing both technical debt and distribution-specific requirements within a one-month development period.
