About

I am a data professional with a Master of Information Technology from Monash University. I finished with Distinction. My work is dashboards, databases, and data visualisation.

Much of my work lives in Excel and VBA, where I automate reporting and link charts to live data. I also analyse data in Python and R, query with SQL, and design dashboards in Tableau.

I care about clean data and honest charts. I have cut manual data work by 40% with macros and built real-time dashboards that teams check daily. Want to see the work? Scroll down to my projects.
