• Main ML POC for Gift Card WW. In 2022, increased the Gift Card system automation rate by 50% keeping bad debt constant, and in 2023, made system enhancements resulting in net $3 MM annual bad debt reduction for Gift.
• Developed a low latency LLM solution to generate email fraud risk scores, resulting in $1 MM bad debt savings annually. Presented research presentation, providing strategic direction for the team.
• Onboarded a system utilizing coupled LSTM model leveraging customer browsing behavioral data, resulting in 10% incremental system automation.
• Developed an LLM solution based on data seen by fraud investigators with 5% incremental system automation.
• Onboarded new system data sources, including cobrand (CBCC/PLCC) CC signals, resulting in incremental annual GMS savings of $13.8 million and 780k annual bad debt savings.
• Developed an autogenerated report for measuring operational workload as measured by ticketing system metrics.

• Designed a T5/Roberta based closed domain question answering pipeline extracting features from a corpus of contract text
• Developed an ML system to rank order medical school applicants for a large medical school, enabling rank ordering applicants and predicting 10% of the applicants who would likely fail to acquire a residency.
• Developed solr based search engine for a company database. Evaluated against ANN based approaches using txtai and implemented autosuggest functionality.
• Led a team of junior scientists to build an E-sports influencer recommender system. Developed data pipeline including web scrapers with Scrapy/Splash to asynchronously parse Twitter, Instagram, Social Blade, and Twitch.

• Used and developed methods of parameter estimation in dynamical systems using analogies with the path integral in quantum mechanics. Learned about topics in nonlinear programming including ill conditioning, newton’s.
• Identified differences between diseased and healthy neurons consistent with clinical observations of Alzheimer’s patients using estimated parameters in dynamical models of neurons.
• Established a mapping between configurable and true parameter values on neuromorphic VLSI chip, leading to emulation of a biological neuron on VLSI hardware for the first time.
