Experience
Sentiment Analysis Bot
https://github.com/shanglun/SentimentAnalyzerFor my article for the Toptal Engineering blog, I built an email-and-texting bot to analyze incoming emails for sentiments and send out alerts as needed.
I use Python, Flask, Apache Thrift, Java, and Stanford's NLP Library. I also used SendGrid and the Twilio API to build email and text message integrations.
