01. About Me

I'm a problem solver who loves good stories. I discovered the beauty of mathematics in 7th grade through logic games, eventually earning medals at national and international math competitions, including the International Mathematical Olympiad (IMO).

Now at Macalester College, I'm applying the same curiosity and discipline from math to programming and data analysis. I'm passionate about turning abstract mathematical ideas into practical, human-centered tools.

I believe the problem-solving mindset and analytical skills I've built through mathematics will help me succeed and adapt in the ever-changing world of technology.

Technologies I've been working with:

  • Python
  • JavaScript
  • C
  • Java
  • C++
  • R / R Studio
  • SQL
  • TypeScript
  • HTML & CSS
  • React
  • Node.js
  • Git & GitHub

05. My Story

01 My Background

I grew up in the northernmost rural part of Mongolia, where it takes a full day to reach Ulaanbaatar, the world's coldest capital. Life there wasn't extraordinary; people mostly minded their own business. My parents were no different. They had never left our town or gone to college, but they provided me and my sister with a happy childhood. At first, this seemed like a limitation, but I now see it as my greatest advantage. Because they had never experienced college or life abroad, they never hesitated to let me chase every opportunity I could find.

That freedom allowed me to study math for hours without interruption, even though I was the strongest at home and could have helped with physically demanding chores. Eventually, it opened doors I could never have imagined. I moved alone to the capital to attend one of Mongolia's most prestigious high schools after winning a silver medal at the national math olympiad, which came with a full scholarship. This was during Covid, and living alone at such a young age was one of the hardest challenges I had faced. But it also gave me focus. I pursued my high school dream: to be selected as one of the six top math students in the country, represent Mongolia, and win a medal at the International Mathematical Olympiad. I did. I fulfilled my dream, and I was ready for the next chapter.

Growing up in a rural town, I had never realized the importance of English. No one around me spoke it, except my older sister in later years. Luckily, the principal of my high school noticed my determination and encouraged me to apply to United World College in Maastricht, Netherlands. For two years, I lived among students from around the world, learning English, embracing new cultures, and discovering who I could become. Those years changed me the most. I went from a boy leaving his country for the first time to someone confident in facing any challenge, making friends across six continents.

Now, I'm in the U.S., studying at a liberal arts college. I'm exploring a wide range of subjects, from art history and environmental studies to economics, and discovering new passions in computer science and data science. I'm meeting people from different backgrounds, learning from them, and shaping the next chapter of my life. I'm not here because I was born into wealth or privilege, but because of supportive parents, inspiring teachers, and friends I could always count on.

In short, I'm rooted in nomadic traditions, shaped by Soviet echoes, guided by Asian philosophy, all while embracing a Western mindset.

02 Interests & Hobbies

๐Ÿ“ธ

Photography

"Practicing an art, no matter how well or badly, is a way to make your soul grow, for heaven's sake." โ€” Kurt Vonnegut

I like observing my surroundings and listening to the sounds of life. Photography is a form of art I enjoy that helps me remember and store these moments. Sometimes I simply take out my phone to capture sudden moments, or go on a walk with my camera to explore the beauty around me. I'm always learning and experimenting, but I've realized I'm less interested in becoming a professional and more in following my feelings, letting my art grow naturally as I experience the world.

๐Ÿ€

Basketball

"Three seconds left, Batsambuu catches the ball, three, two, one, he shoots it, BANGGG! BUZZER BEATER!"

This is how seven-year-old me used to imagine and commentate on myself while playing basketball (using socks as a ball and a chair as a basket) after watching the 2010 NBA Finals. One player, Kobe, stood out from the rest and became the best player in the finals. That's when I first realized what a great sport basketball is, seeing the joy he brought to twenty thousand fans at Staples Center. Since then, I've enjoyed everything about basketball: playing it, watching it, exploring the stories around it, and even video games about it.

๐ŸŽฎ

Video Games

"Wanting something does not give you the right to have it." โ€” Assassin's Creed 2

Video games are my way to relax and take a break from reality. I often prefer a good game over a movie or a book, because they beautifully combine art and technology. They teach lessons, evoke a wide range of emotions, and let you experience things you'd never do in real life. I find myself arguing with friends over their choices in a game, focusing on puzzles, or riding a horse across the open world of Ancient Egypt. It's a unique form of storytelling that truly makes you part of the story.

03 My Beliefs & Views

On Education & Teaching

I believe that better education is the key to creating a better world. I have studied in a rural public school, a prestigious private school, an international boarding school, and now at a liberal arts college. Each experience taught me something different about the power of good education. Because of these experiences, I believe education should be accessible to everyone. It has become a central part of my dream to build a world-class educational institution, giving more children the chance to discover and pursue their passions and dreams, no matter where they are born. To take steps toward that dream, I have been tutoring high school students in Mongolia as much as I can, sharing everything I know and helping them grow.

On Other Things

I'm still gathering my thoughts. More of my beliefs and ideas will be added here soon.
