About

Professional summary

I am a BSc (Hons) Artificial Intelligence undergraduate with practical experience in data analytics, machine learning, database management, and business intelligence reporting.

I work with Python, SQL, Power BI, Excel, Power Query, and DAX to prepare data, build ETL pipelines, create data models, and develop interactive dashboards that support actionable decisions.

I have completed end-to-end machine learning projects using real-world datasets, including classification, forecasting, clustering, anomaly detection, and computer vision. My work includes evaluating models with accuracy, R-squared, precision, recall, F1-score, and cross-validation metrics.

I have also designed normalized SQL Server databases, created role-based reporting queries, and applied relational database design principles such as normalization, integrity constraints, and CRUD operations.

I am seeking a Data Analyst internship where I can apply my analytical, technical, and problem-solving skills to transform data into meaningful business insights while continuing to grow in a professional environment.

Career history

Data Analytics and BI - Warehouse Inventory Academic Project

I designed an ETL pipeline using Power Query and developed a snowflake schema data model for warehouse inventory analysis.

I created DAX measures for total revenue, average price, and total quantity, then produced a 10-visualization Power BI dashboard covering stock, pricing, and warehouse KPIs.

Machine Learning - Hotel and Tourism Systems Academic Project

I developed an end-to-end machine learning pipeline using 119,000 real-world records for hotel and tourism analysis.

Logistic Regression achieved 82.0% accuracy for cancellation prediction using 5-fold cross-validation, while an ANN achieved 92.7% R-squared for revenue forecasting. I also used K-Means and DBSCAN to identify three customer segments and HBOS anomaly detection to flag 1,168 anomalous bookings.

Healthcare Database Management System Academic Project

I designed a nine-table, 3NF-normalized Microsoft SQL Server database for Kandy General Hospital.

I implemented integrity constraints and wrote eight role-based SQL reporting queries to support hospital data management and reporting needs.

HomeVision - Indoor Scene Recognition Academic Project

I built a five-class indoor image classifier using transfer learning and the MIT Indoor Scenes Dataset. The model classified kitchen, bedroom, bar, living room, and warehouse scenes.

I evaluated three CNN architectures: ConvNeXt-Tiny achieved 92.77% test accuracy, EfficientNetB0 achieved 91.53%, and ResNet50 achieved 90.50%. I used class-wise precision, recall, F1-score, confusion matrices, and a 70/15/15 train-validation-test split for model selection.

Machine Learning - Automobile and Transport Systems Research Academic Project

I led the classification domain of a group systematic literature review based on 20 peer-reviewed sources. I reviewed YOLO, R-CNN, and SVM approaches for vehicle detection and road-surface classification.

I co-proposed IITMS, a four-layer machine learning pipeline incorporating SHAP interpretability for real-time transport deployment.
