Projects

COVID-19 Death Growth and Number of Healthcare Facilities in Indonesia

This project aims to find out the correlation between COVID-19 metrics, in this case, death growth, with the number of public healthcare facilities in 34 provinces all over Indonesia. We used several datasets which were collected from several reliable sources.

Telecom Churn Prediction

To achieve these goals, the project will collect and analyze customer data, including demographic information, service usage data, and transaction data. Then, data analysis techniques such as machine learning (3 models) will be used to build accurate churn prediction models.

Netflix Dashboard

Netflix, as the top internet-based entertainment provider, has 158 million paid subscribers across 190+ countries who enjoy a diverse range of TV shows, documentaries, and movies. My curiosity prompted me to analyze Netflix's content and create interactive visualizations using Tableau.

[Dashboard] King Country House Sales

In this project, I learned to create interactive filters connected to specific dashboard sheets, enabling a focused drill-down while maintaining an overview. For instance, the Month/Year filter displays average house prices trends, while a calendar widget offers detailed daily sales insights.

Road Accident Dashboard

This dashboard shows yearly UK accident data, allowing filtering by year and severity, comparing previous and current years. It presents casualties by vehicle and road category, and locates fatalities based on weather and road conditions.

HR Analytics Dashboard

This dashboard provides a comprehensive overview of essential KPIs, aiding HR teams in assessing satisfaction, age-group demographics, gender-specific attrition rates, and workforce attrition by field.

Emotion Recognition

Classification of a person's emotions using recorded sound. Talking is a common way to express an expression or emotion. Voice can give an idea of a person's emotions based on tone and pitch.

Bike Sharing
