Developed Russian pluralization support for the i18n TP function in the go-vikunja/vikunja repository, enabling accurate handling of up to four plural forms based on count and translation choices. This work involved implementing Russian-specific pluralization rules and integrating them into the existing translation pipeline using Go. By addressing the requirements outlined in issue #1334, the changes improved localization accuracy for Russian-speaking users and streamlined future maintenance of the translation system. The project leveraged skills in Go development, internationalization, and localization, resulting in a more user-friendly Russian UI and reducing the ongoing effort required for managing language-specific plural forms.
