Worked on the AIS-SNU/AIS-lab-website repository to refresh the DataFreeShield citation asset, replacing the citation thumbnail from PDF to PNG for improved rendering in citations and listings. The update involved managing image assets and editing YAML metadata within sources.yaml to reference the new PNG file, ensuring consistent display across the site. Leveraged skills in data management, documentation, and Git-based version control to validate changes through the asset pipeline and site views. This work enhanced citation accuracy, branding consistency, and user trust, addressing a targeted feature request without introducing bugs or regressions, and demonstrated a focused, detail-oriented approach to documentation updates.
