Work Experience

Walmart

Senior Manager, Data Science

Walmart

April 2025 - Present
Bentonville, AR
  • Walmart e-commerce middle-mile network optimization — Developed a MIP model for optimizing SKU placement across Walmart next-gen and conventional FCs. — Coordinated in developing a multi-commodity fixed-charge network flow model for designing 2-tier storage facilities.
  • Sam’s Club New Asset Strategy — Developed machine learning models to predict market penetration and potential GMV lift at the H3 geo-spatial resolution. — Designed mathematical model and heuristics to identify optimal site placements across the U.S., maximizing business GMV. — Built an interactive Streamlit dashboard enhanced with generative AI capabilities to present analytics to executive stakeholders.
Walmart

Senior Data Scientist

Walmart

January 2022 - March 2025
Dallas, TX
  • Walmart e-commerce middle-mile network optimization — Coordinated architectural design of a multi-commodity network flow model optimizing the middle-mile e-commerce framework (improving 1/2-day delivery rate by 7-10% in FY26, driving a $250M GMV lift). — Developed an XGBoost model leveraging spatial features to predict inefficient paths, filtering them from large-scale execution space to cut model runtimes by 30%.
  • Walmart e-commerce last-mile network optimization — Engineered a multi-channel location-routing engine to construct parcel station delivery layouts (Projecting $450M in transportation efficiency savings by FY30). — Created mixed-fleet optimization algorithms to identify ideal asset deployments inside dynamic station lines ($26M projected savings). — Designed store-clustering layers to scale Available-To-Sell (ATS) metrics (~20%+ optimization curve across nodes).
Mississippi State

Graduate Research Assistant

Mississippi State University

September 2018 - December 2021
Starkville, MS
  • Developed mathematical models and heuristic algorithms for electric vehicle routing, biofuel operations, and complex drone logistics layouts.
  • Implemented hybrid decomposition schemes inside Gurobi to execute heavy stochastic optimization frameworks.
  • Built production machine learning architectures (Random Forest, Naïve Bayes) translating biological matrices into active predictions with 90% accuracy.
