Worked on the yaizu-city/opendata repository to update the Announcements section, replacing outage-resolution messaging with information about the new 'Let's Measure Vegetable Intake' health initiative. Focused on front-end development using HTML, the update promoted Veggie Check devices available in local stores and informed citizens about a new public health service. The approach prioritized a proactive content strategy aligned with Smart City goals, shifting the focus from system outages to community health engagement. Delivered the feature as a single, low-risk commit to ensure stability and minimize deployment risk, laying the foundation for broader citizen information channels within the platform.
