Key Achievements• Drove ideation, design, development and deployment of an online Entity Resolution system providing visibility into $1.2B+ in disparate customer revenue across 13M accounts through business logic, NLP, Similarity Search via LLM, and graph analytics• Ranked 50M customers via classification/regression to identify 360k marketing targets worth $1.02B in expected revenue• Classified the churn risk of 710k customers with 93% Recall and revenue impact of $46.2M to advise outreach• Determined drivers of customer satisfaction by analyzing 3k surveys using NLP, clustering, regression to inform call center reps• Applied Interrupted Time Series method to customer revenue forecasting to account for $282M Covid-19 revenue impact• Used quasi-experimental Synthetic Control Method to measure ~$400M in annual benefit from exclusive service offerings• Implemented Change Point Detection model to help the client capitalize on early recognition of sector revenue trends• Segmented customers into tiers via clustering in effort to provide levels of service that prevent churn and encourage spend• Engineered 80+ data features for lead generation and ranking models through complex SQL/SAS queries• Piloted Informatica Enterprise Data Catalog tool to develop 100+ data assets, connecting 7 data silos• Integrated 26 tables across 5 HR vendor systems to help improve visibility for candidates and reduce time-to-hire by 30%Additional Responsibilities• Grew account billings by $1.1M+ through sale of new solutions by developing client relations and proving technical capabilities• Presented analytics solutions/insights to clients and handled technical inquiries as lead data scientist and architect• Hired and mentored junior data scientists, multiplying team’s impact by broadening scope and growing depth of solutions• Led team by architecting solutions, improving internal processes, removing blockers, and encouraging training opportunities

• Utilized 4M+ records of aviation operation communications to assess the criticality of notifications airmen receive to support prioritization, and translated the heavily abbreviated and technical language into laymen terms for easier consumption• Integrated external data for aviation abbreviations and QCodes, performed NLP preprocessing, used GPT 3.5 Turbo to produce training/validation data, and fine-tuned LLMs (FLAN-T5 and Deberta) for their respective translation and criticality tasks • Translation model improved 15-20% on ROUGE metric over stock FLAN-T5; Criticality MAE decreased 11% compared to literature

• Performed time studies to collect data regarding a manual visual inspection process of catalytic converter cores used in various types of vehicles• Utilized data to construct parameters for an inspection line simulation model • Developed an inspection line simulation model using Simul8 software to allocate labor resources to the inspection line based on the production demand that day• Reduced labor hours spent on the inspection line during times of low demand to achieve savings in the quality assurance process

Multiple Facilities Across Us

• Performed time studies and data analysis of labor standards at multiple high-volume distribution facilities across the U.S.• Validated Warehouse Management System parameters and recommended warehousing logistics process enhancements• Collaborated across the organization (engineering, facility management, labor unions) to achieve program objectives
