Mathematics undergraduate, olympiad coach, and author.
My interests lie in number theory, Euclidean geometry, and mathematical olympiad education. I am currently completing my undergraduate thesis at Universitas Brawijaya, coaching olympiad students, and developing mathematical learning resources.
Mathematics, writing, and education
A selection of the work that best represents what I am currently building and contributing to.

The Art of Olympiad Geometry
An Indonesian-language book that builds a foundation in olympiad geometry and introduces a broad range of problem-solving methods and perspectives. It is written for students who want to understand the reasoning behind a solution, not merely its final steps.

I teach olympiad mathematics across different school levels and have contributed to Indonesia's national International Mathematical Olympiad training program.

Set-valued analysis
My undergraduate research compares algebraic and metric approaches to differentiability for set-valued functions.
Algebraic counting
I am also exploring questions in algebraic counting and matrix theory.
Olympiad geometry
I continue to explore Euclidean methods, write problems, and develop materials for mathematical olympiad training.
A few milestones
Why geometry?
Geometry was the first area of mathematics that genuinely fascinated me. I discovered olympiad geometry in junior high school, and its combination of visual intuition, elegant transformations, and surprising structure has stayed with me ever since.
What began as curiosity eventually grew into years of learning, teaching, problem writing, and writing The Art of Olympiad Geometry.
Let's talk mathematics.
I am always happy to discuss mathematics, olympiad education, teaching opportunities, or possible collaborations.
