I'm an IB Diploma Programme Computer Science and Mathematics teacher at an international school in Vietnam, with a background spanning curriculum design, assessment, and educational technology. I teach IB DP Computer Science, Mathematics AI SL, and MYP Mathematics. Before moving into the international school world, I worked as a mathematics coordinator in Australia, where I led curriculum mapping across the full year range. That systems-thinking background shapes how I approach everything I build -resources included.The materials I publish here come directly from classroom use.
