Hi, i'm Nanda.
Data Analyst
Turning Data Into Clear Insights 

Skilled in SQL, Excel, Power BI, Tableau and Python

ABOUT ME

I am an Informatics graduate with a strong interest in data analysis and data-driven problem solving. I have experience in processing, cleaning, and analyzing data using SQL, Python, and visualization tools such as Tableau and Power BI to generate clear and meaningful insights.

I am experienced in performing exploratory data analysis (EDA), data cleaning, and dashboard development to support data-driven decision making. I also have a foundation in data mining and machine learning concepts, including diagnostic, predictive, and prescriptive analysis.

I have worked with datasets from various domains such as sales, transportation, and business operations. I enjoy exploring data end-to-end — from data preparation and SQL querying to transforming analytical findings into visual insights through dashboards.

Currently, I am continuously developing my data analyst portfolio and strengthening my analytical skills to deliver accurate, practical, and impactful insights that support business decisions.
