Services
I provide data-driven solutions that combine analytical skills with real business experience — from data analysis and machine learning to administrative management and organizational support.
Data Analysis & Visualization
Performing end-to-end data analysis using Python (Pandas, NumPy, Matplotlib, Seaborn, Plotly) and SQL. I conduct exploratory data analysis (EDA), statistical testing (Pearson & Spearman correlation, normality testing), outlier detection, and build interactive dashboards using Tableau and Looker Studio.
Learn MoreMachine Learning Modeling
Building classification and prediction models using Scikit-learn, XGBoost, and LightGBM. Services include feature engineering, preprocessing pipelines, hyperparameter tuning, class imbalance handling (SMOTE, NearMiss), and model evaluation using Recall, F1-Score, PR AUC, and ROC AUC — as applied in travel insurance claim prediction projects.
Learn MoreCustomer Segmentation & RFM Analysis
Profiling customer behavior using RFM (Recency, Frequency, Monetary) analysis and CV-based behavioral segmentation. I generate segment-specific business recommendations to optimize targeted marketing strategies and improve customer retention using Python, Pandas, Matplotlib, and Seaborn.
Learn MoreTime Series Forecasting
Building stock and demand forecasting systems using SARIMA and Prophet models with ensemble learning. I apply AutoARIMA optimization, seasonal trend modeling, and evaluate performance using MAE, RMSE, MAPE, and R² — deployed as interactive Streamlit dashboards with Plotly for real-time stock analysis on IDX equities.
Learn MoreNatural Language Processing (NLP)
Scraping and analyzing Twitter/X data using NLP techniques to identify public sentiment, trending topics, and dominant narrative patterns. Results are used for editorial strategy development, brand monitoring, and content planning — delivered using Python, Pandas, and NLP libraries.
Learn MoreAdministrative & Data Management
Supporting organizational efficiency through structured document management, reporting, and business process documentation. With experience at Bank Indonesia and Bank Ganesha, I provide services in governance documentation, compliance reporting, operational data coordination, and CRUD-based data management systems using Python, Excel, and Google Sheets.
