During July 2025, contributed to the UCSD-E4E/weekly_presentations repository by developing a new Mel Spectrogram Visual Slide to enhance the clarity of audio feature extraction concepts in educational presentations. Leveraging LaTeX for presentation development and technical documentation, the work included integrating a custom image asset to visually demonstrate Mel spectrograms. This addition established a reusable slide component, supporting consistent and effective communication of technical material in future decks. The approach focused on improving instructional value and visual coherence, addressing the need for clear, illustrative content in technical presentations without introducing new bugs or requiring extensive changes to existing materials.
