   Built and maintained AMT Global Workshop App and Gemba Tool using Express.js, React, Node.js, and SQL, delivering scalable, interactive, and data-driven solutions to enhance operational efficiency and real-time workshop management. Designed and optimized ETL pipelines and dashboards for sales trend analysis, enabling accurate demand forecasting through time-series modeling and anomaly detection. Engineered a search and recommendation service by leveraging ranking algorithms and semantic search techniques (TF-IDF, BM25), significantly improving the identification of warranty-related services and reducing search errors. Developed an ISL prediction model using machine learning algorithms including Random Forest (RF), CatBoost, and LightGBM, and optimized model performance using Grid Search and cross-validation, accurately predicting whether a part should undergo production. Applied feature engineering, model evaluation metrics (ROC-AUC, F1-score), and model interpretability techniques (SHAP, LIME) across projects to ensure robust and explainable machine learning outcomes.
