Developed a Slack bot using the Slack Bolt framework to find subject matter experts for a given search query based on the relevancy of their channel posts as part of the Industries Hackathon at Salesforce
Used various channel, messaging, event APIs, and features of Slack to allow the bot to obtain message content of posts and interact in the channels
Added a feature allowing the bot to summarize the text of a PDF document attached to a post in a few sentences; utilized the sentence-transformers library to achieve this
Learnings - Python, Slack Bolt, Sklearn, Sentence-Transformers
