Work Experience

Senior Software Engineer / Senior Data & AI Engineer at Spring Health
October 1, 2022 - October 1, 2025
Owned the design, development, deployment, and operational support of Python-based data services, backend workflows, and AI-powered systems supporting patient navigation, analytics, support automation, and internal decision-making. Built healthcare data workflows to ingest, transform, validate, and serve structured and unstructured data across product, analytics, clinical operations, and AI use cases. Implemented production-ready backend data services using FastAPI/Flask/Django, PostgreSQL/Redis, AWS, REST APIs, and GraphQL for reliable access to governed, reusable data. Developed data quality checks for completeness/consistency/accuracy/freshness and schema integrity, plus reusable Python components for transformations, automation, validation, and reliability. Built and deployed RAG workflows using GPT-4/GPT-3.5/Claude/LLaMA with LangChain/LangGraph, Pinecone/FAISS, semantic search, and vector embeddings, and integrated MCP-style data access patterns to provide governed context to LLM
Computer Vision Engineer / Python Data Engineer at TekValue IT Solutions
December 1, 2018 - August 1, 2022
Designed and implemented Python-based data and AI pipelines for a face recognition employee access system supporting secure authentication across enterprise environments. Built end-to-end unstructured image workflows: ingestion, preprocessing, detection, alignment, embedding extraction, validation, similarity matching, and audit logging. Developed backend services using Flask/FastAPI and API integrations for employee enrollment, identity verification, access decisions, and operational reporting. Fine-tuned and adapted pre-trained computer vision models (RetinaFace, ArcFace) for real-world lighting/pose/occlusion, and built inference/model workflows using OpenCV, PyTorch/TensorFlow, Scikit-learn, Hugging Face, ONNX Runtime, and CoreML to improve deployment readiness. Implemented embedding-based authentication with cosine similarity and calibrated thresholds, improved inference latency (~25%), and added monitoring/continuous improvement for edge cases. Implemented privacy-conscious stora
Data Scientist / Data Engineer at Walmart
December 1, 2016 - November 1, 2018
Built and maintained production ETL pipelines using Python, SQL, Apache Airflow, Kafka, and Spark to process large-scale retail data for analytics, reporting, and business decision-making. Developed batch and near real-time workflows for clickstream, transactions, customer behavior, search, cart, sales, and inventory datasets. Created scalable transformation logic with Python/SQL/Spark/Pandas/NumPy and reusable pipeline components to convert raw operational data into analytics-ready datasets. Developed dbt-style modular transformation models and SQL reporting layers to standardize business metrics. Created curated analytics-ready models and tables to support Tableau/Power BI/Streamlit/D3.js dashboards and internal reporting. Optimized Snowflake/PostgreSQL schema design, queries, indexes, and reporting tables to improve performance and reduce dashboard latency. Implemented validation checks (missing records, duplicates, inconsistent metrics, freshness delays, schema issues) and develope
