• Search Intent Classification Modeling Project
• Created NLP classification models that bucket any search query into groups based on client-defined taxonomy to glean insights on what queries the client is winning, wasting on, and have the potential to grow on
• Implemented data pre-processing using tokenization and count vectorizer with stemming and lemmatization then trained the data with classification models Anomaly Detection Project
• Built an anomaly detection machine learning model using Prophet package in python for various digital marketing KPIs (key performance indicators) such as impression, clicks, conversion, clickthrough rate, and cost per.
• Automated the anomaly detection processes to run every day from pulling data in google bigquery to delivering anomaly notifications in slack using cronjob
