Worked on expanding cross-platform compatibility for the nextcloud/talk-desktop repository by implementing Windows ARM64 build support. Developed and integrated new build scripts using JavaScript and Node.js, updating the build configuration to include ARM64 as a target and modifying packaging scripts to support ARM-based Windows devices. This work enhanced the CI/CD process by ensuring ARM64 builds are included alongside existing targets, laying the foundation for future ARM-focused releases. The approach demonstrated disciplined version control and build automation skills, resulting in broader device compatibility and improved release readiness for ARM64 platforms, though no major bug fixes were addressed during this period.
