BarryNguyen2003/README.md

Hi, I'm Barry (Xuan Hoang Nguyen) 👋

Data Science & Marketing graduate based in Sydney, looking for a data analyst / data science role where I can turn messy data into decisions.

I studied a double degree — BSc Data Science + BBus Marketing at Western Sydney University — so I'm comfortable on both sides: the modelling and the business question behind it. I have full working rights in Australia (subclass 485).

  • 🔭 Open to junior data analyst / data science roles in Sydney
  • 🌱 Currently sharpening Python, Power BI and SQL
  • 💬 Ask me about turning a raw dataset into a clear, decision-ready story

Tools I work with

Python · R · pandas · scikit-learn · Tableau · Power BI · Excel · data cleaning · machine learning · data visualisation

A few things I've built

Project What it is
AI Analytics System An agentic pipeline that cleans data, trains and compares ML models, and writes a report
Global Health Inequality A Tableau dashboard exploring health gaps across countries using WHO data
Wine Quality ML Regression, classification, and clustering on the UCI wine dataset in scikit-learn
Home Sales Dashboard An interactive HTML/Chart.js sales dashboard on 9,999 orders — finds a 33% cancellation rate as the core revenue leak (live)
