Worked on enhancing localization quality for the arendst/Tasmota repository, focusing on updates to the Traditional Chinese (zh-TW) web UI translations. Applied expertise in software internationalization and translation to improve font rendering, readability, and consistency across interface strings, particularly those with numeric suffixes and sensor type labels. Incorporated feedback from testing to refine the localization workflow, reducing translation churn and increasing QA readiness. Utilized C and C++ in the process, ensuring that updates integrated smoothly with the existing codebase. The work aimed to deliver a more accessible user experience and expand localization coverage to support broader market adoption.
