## About

```text
On Upwork, I collect, clean, and analyze large datasets using SQL, Python, and Excel to improve data accuracy and support business decisions.

I designed and maintained automated Power BI dashboards tracking CAC, ROAS, and lead conversion, reducing manual reporting time by 50%. I also developed a K-Means clustering model that refined audience segmentation and improved campaign CTR by 18%.

For my E-Commerce Performance Dashboard project, I built an interactive Looker Studio dashboard with SQL to track revenue, order trends, category sales, and refund rates across Shopee, Tokopedia, Lazada, and Blibli.

My projects also include analyzing global suicide data and Global Terrorism Database records, then creating visualizations and an interactive Power BI dashboard. I’m studying Informatics Engineering at University of Darussalam Gontor, with a focus on Data Science and Business Intelligence.
