Hello! I'm Cakra Wangsa, an Information Technology student and data enthusiast focusing on data analysis, data mining, and data science.
I enjoy transforming raw data into clear insights, building reliable models, and telling the story behind the numbers through effective visualizations.
I believe data is more than just numbers it’s a medium to make better decisions and create real-world impact. I’m always open to new challenges, collaborations, and constructive discussions to grow together.
Currently, I’m actively working on projects around:
- 📊 Exploratory Data Analysis (EDA) & visualization for actionable insights
- 🤖 Machine Learning (classification, regression, clustering, time series)
- 🧠 Model Explainability (feature importance, SHAP)
- 🗂️ Data Cleaning & Feature Engineering
- 🧪 Experiment Tracking & Reproducible Pipelines
- Spreadsheet & BI: Excel (PivotTable, Power Query, Data Analysis ToolPak), Google Sheets, Looker Studio
- Python Analytics: Pandas, NumPy, SciPy, scikit-learn
- Visualization: Matplotlib, Seaborn, Plotly
- SQL Databases: MySQL, PostgreSQL, SQLite
- Environment: Jupyter Notebook, VS Code
- Versioning & Dev: Git, GitHub, Linux, Docker
- Deep Learning: PyTorch, TensorFlow
