What I've built.
Arin — AI Budget Analysis Assistant
AI-powered government budgeting assistant built with Streamlit and Gemini API. Retrieves financial data from 8 Excel sheets, performs automated SBM calculations, and generates structured budget tables. Deployed and actively used for internal financial workflows at BPPK Kemenkeu.
E-Commerce Customer & Sales Analytics
End-to-end analytics pipeline on 100k+ orders across 9 datasets. Includes data wrangling, feature engineering, RFM customer segmentation, revenue trend analysis, and geospatial mapping — delivered through an interactive multi-tab Streamlit dashboard.
Employee Travel Activity Dashboard
Interactive Excel dashboard with PivotTables and slicers to monitor 300+ official travel assignments across 94 employees over a 2-month period. Used in production at BPPK Kemenkeu to support structured HR reporting and compliance tracking.
Employee Assignment Analytics — Power BI
Power BI dashboard built from the same employee travel dataset — visualizing assignment distribution by team, monthly trends, and employee workload. Demonstrates cross-tool fluency: the same data source explored through both Excel and Power BI for different reporting needs.
Bank Transaction ML Pipeline
Full end-to-end ML pipeline on 2,538 bank transactions — preprocessing, feature engineering, clustering, and classification to identify transaction patterns and surface analytical insights. Built with Scikit-learn from raw data to evaluated model.
CNN Rock–Paper–Scissors Classifier
Image classification model using TensorFlow and VGG16 transfer learning with data augmentation, callbacks, and ImageDataGenerator pipeline. Achieved over 97% accuracy on the Dicoding dataset — full training pipeline built from scratch.
