Antonika V. contributed to both the NixOS/nixos-homepage and golang/website repositories, focusing on front end development and technical documentation. In March 2025, Antonika updated the NixOS homepage to accurately display the current package count, ensuring users see up-to-date information about the ecosystem. On the golang/website project, Antonika enhanced the Getting Started tutorial by refining formatting and clarifying command usage, which improved onboarding clarity for new users. These changes were implemented using Astro and HTML, demonstrating attention to detail in both content accuracy and user guidance. The work addressed specific user-facing issues with targeted, maintainable code and documentation updates.
