Capability required intensive research into multiple legacy systems to identify and combine relevant datasets, tight integration with SMEs to validate methodology and form shared definition of the problem. I used a UI-based annotation tool (Prodigy) to gradually build the interface and required data for engineers to complete the desired task, leading to training and validation data for an automated model.- Initiated and led a foundational effort to apply Transformer models on multiple text-based tasks across the organization. This included development of a massive business-wide and domain specific corpus, including many data sources previously unavailable in a structured format, conversion of multiple domain problems into "tasks", core pre-training and task fine-tuning of Bert and Roberta based models. Derivative models from this effort have been deployed to assign ATA codes to log page findings and for recommending manual pages to support mechanic troubleshooting and engineering research.

This supported identification of potential insider threats and targets. - Created and led development of an internal tool called "Scout", which applied computer vision to support security operations, specifically for identifying when known suspicious 3rd party websites changed visually to support a spoofing attack. Real time alerts were delivered via a Microsoft Teams bot to a shared channel including relevant Security and Legal stakeholders.- Research analyzing change patterns for OneDrive/Sharepoint file contents over the course of operation sequences (e.g., Update, Modified, Shared, etc.). This supported detection of malicious data exfiltration patterns. - Incident response data analysis for multiple security incidents, such as Log4J and Solarwinds events. Show less
