Experience

Data Scientist

Mahindra & Mahindra, Bengaluru
Apr 2023 - Present · 3 years 3 months

Developed a machine learning pipeline in Python, employing boosting techniques to enhance model accuracy.
Addressed class imbalance using advanced sampling techniques, including SMOTE and Tomek Links, increasing model precision from 76% to 85% and reducing engine test failures by 15%.
Containerized the pipeline using Docker and leveraged AWS Lambda to process real-time data from PostgreSQL triggers, enabling consistent, scalable deployments.
Designed and deployed an AI-powered multilingual sales enablement platform using AutoGen agent and Azure AI, integrating NLP to automate personalized pitch generation tailored to regional languages.
Utilized a Neo4j knowledge graph database to structure and retrieve interconnected data on regions, retailers, incentive schemes, and historical performance for intelligent pitch customization.
Achieved a 40% reduction in pitch preparation time, accelerating sales team responsiveness.
Engineered a real-time defect detection system for mechanical dies using YOLOv8, a cutting-edge object detection model in computer vision, achieving 90% accuracy for precise defect localization in manufacturing.
Built and deployed an end-to-end data pipeline by annotating 5,000 die images using LabelImg, applying OpenCV for image preprocessing, and storing data in a structured format for efficient model fine-tuning.
Reduced sheet metal part rejections by 20–30%, minimizing material wastage and improving efficiency.
