ZinZinAyeChan/README.md

Hi, I'm Zin Zin 👋

I'm a data enthusiast based in Sydney.

BCom graduate in Business Analytics and Accounting from Macquarie University.

I analyse customer and sales data, build models, and turn findings into recommendations that people actually act on. I've presented to clients, teams, and senior leadership and I know how to make data make sense to a non-technical audience.

What I've built: Interactive dashboards for a real client. Customer segmentation models. Price prediction models. Time series forecasts. Regression and ANOVA analyses. All with a clear business recommendation at the end.

What I do: SQL querying · data cleaning · exploratory data analysis · statistical modelling · machine learning · dashboard design · stakeholder reporting

Currently working on: Practising SQL on real datasets · publishing dashboards to Tableau Public · learning machine learning and AI fundamentals

Feel free to browse my work, connect, or just drop a message!
