Worked on the openwrt/packages repository to implement modular packaging for jq, delivering both a lightweight version without regex support and a full-featured variant with oniguruma-based regex integration. Updated the Makefile-based build system to automate the creation of separate, feature-tagged packages, allowing users to select the appropriate version for their device constraints. This approach enabled reduced image sizes for lightweight deployments and clearer maintenance boundaries between package variants. Demonstrated skills in build system configuration, package management, and external library integration, focusing on automation and flexibility to support diverse user requirements within the OpenWrt ecosystem over the course of the month.
