Worked on the Pearson-Advance/edx-platform repository to enhance privacy and performance in the notes feature by disabling LLM-based summarization by default. This was accomplished by removing the llm_summarize plugin from the default AnnotatorJS plugins, reducing unnecessary large language model usage and minimizing data exposure in user notes. The change was implemented through a focused JavaScript commit that centralized plugin configuration, making future maintenance and audits more straightforward. With a primary emphasis on front end development, the work aligned with a privacy-by-default strategy and contributed to lower compute costs, while ensuring the feature remained robust and easy to review.
