Hi, I'm Dao —
I turn messy data into clear decisions.

Based in Bangkok, I'm a Data Analyst who enjoys digging into complex datasets and finding the story hiding inside them. This portfolio is a snapshot of that process — from cleaning raw numbers to building dashboards people actually use. Thanks for stopping by! 🚀

Portfolio

A closer look at what I work on

Six areas that sum up how I like to work with data — a mix of research, modeling, code, and a genuine curiosity for what the numbers are trying to say.

Academic Project

Machine Learning

Data Visualization

Academic Project

Applying rigorous data analysis to real-world social and economic questions. Two studies that turn open data into insight worth acting on.

Forecasting the remittances of overseas Thai workers
Spatiotemporal analysis of alcohol outlet density and teenage drinking behavior in Thailand, 2007–2017

Machine Learning

Building models that forecast outcomes and uncover hidden patterns in data. I move between Decision Tree, K-Nearest Neighbors, Random Forest, and Logistic Regression depending on what the problem calls for.

Coding

Turning raw data into something usable, in SQL, R, and Python. These are the languages behind every query, every clean dataset, and every model in this portfolio.

Data Visualization

Making data easy to read, and easier to act on. I build dashboards and reports in Looker Studio, Power BI, and Tableau that turn numbers into next steps.

Web Scraping

Collecting data at the source, using R and Python. When the answer isn't sitting in a spreadsheet, I build the pipeline that goes and finds it.

Google Sheet

Fast, organized spreadsheet work using QUERY, INDEX, and MATCH. Built for quick answers, without needing to open a full BI tool.
