Machine Learning Engineer
Walmart · Sunnyvale, CA- Led design and development of a hybrid agentic architecture for Sam's Club merchandising using LangGraph, combining Router-Specialist delegation with intra node Planner-Tool-Critic loops. Enabled dynamic context injection and memory aware tool orchestration via MCP to diagnose product availability issues in natural language which reduces investigation time from hours to minutes and supports autonomous remediation with human-in-the-loop control.
- Engineered a 24/7 autonomous support agent with webhook based integration (JIRA, ServiceNow, Confluence, Slack) and a hybrid RAG pipeline using semantic search (OpenAI + FAISS) for context grounded resolution which achieved 95% auto ticket resolution with retrieval enhanced reasoning and zero manual intervention.
- Built and deployed an end-to-end anomaly detection system for 1.4M SKUs, saving $4M+ by flagging pricing and dimensional errors. Integrated a vision pipeline (YOLOv8 + reference scaling) to estimate product dimensions from images, and used LLM-based parsing to extract dimensions from specs sheets. This boosted model accuracy by 38% and cut manual QC by 95%.
- Developed a vision + LLM pipeline to extract nutrition facts from product labels at Walmart and Sam's Club using OCR (Tesseract) and GPT-5 for SNAP eligibility classification.
- Built a dynamic Model Context Protocol (MCP) framework spanning multiple resource tiers enabling self discoverable services and orchestration for agent based automation at scale.
- January 2023 — December 2023
Research and Teaching Assistant (ML, Bioinformatics, and Database)
University of Florida- Processed and analyzed 10+ TB of human genome data to identify genetic patterns associated with ALS.
- Designed a custom statistical framework for novel repeat expansion detection currently under lab validation for clinical research.
- June 2021 — October 2021
Machine Learning Intern
Whizkey- Engineered a signal disaggregation pipeline using NILM techniques and time series ML models, paired with a real time Streamlit dashboard which reduced monitoring overhead and enabled predictive maintenance, extending appliance lifespan in 86% of deployments.
- July 2021 — September 2021
AI and Data Science Intern
Hornbill Labs- Designed an ensemble time series forecasting pipeline with a Plotly analytics dashboard to optimize retail inventory flow-achieved 98% forecast accuracy and delivered comparative model insights for supply chain planning.
