Confidential, SAN JOSE, CA

Data Scientist/Machine Learning Engineer

Responsibilities:

  • Automated and built Machine learning model pipelines using frameworks such as sci-kit learn on user identity security data to detect fraud and deployed them using kubeflow . (anomaly detection) .
  • Developed Deep learning model LSTM(RNN) based on semantic analysis of the text (Natural language processing) to detect potentially malicious typo-squatting/targeted phishing URL and leveraged ASN mappings, WHOIS data patterns, and HTML tag analysis to classify the type of attack with an accuracy of 91%.
  • Built and automated data engineering ETL pipeline over Snowflake DB using Apache spark and integrated data from disparate sources with Python APIs, consolidated them in a data mart (star schema) and orchestrated entire pipeline using apache airflow delivering daily/weekly metric email reports from the power BI server to facilitate on the go decision making for business users.
