• Designed “Smart Monitors” an ML anomaly detection system that alerts customers based on irregularities in their log and metric data.
• Improved Sumo’s text-based clustering product for logs (logreduce) by modifying and distributing their algorithm over 100’s of nodes. My contribution increased the throughput (logs clustered per second) by 10x.
• Created an entity detection transformer for logs, which helped detect apps, services, and agents with few-shot examples.
• Increased frequency of code deploy by a factor of 3x by migrating our team’s services to Kubernetes.
• Created a new open source framework (Open Analytics) that allows customers to plug-in machine learning models into Sumo’s log search interface.

* Created a recurrent neural network (RNN) in tensorflow that estimated various cardiovascular metrics using pressure sensors in a bed. * The RNN successfully removed various sources of noise and identified which sensors produced reliable estimates.

* Created a data-driven regression model for electrically conductive concrete that could predict pressure buildups in oil and gas wells based on electrical signals transferring through concrete.* My data analysis techniques and visualizations were used in reports for investors of the project.

* Created a simple statistical anomaly detection program and lab protocols for testing if samples used in artificial corneas were thermally stable.
