Profile: https://flows.cv/aksana

I am passionate about learning new things and technology that can help others. I can spend hours and hours on an interesting project. I enjoy solving problems and algorithms. I like to deconstruct problems and functions that come my way. I am always curious about how things work and how they are implemented. I also love to find solutions with different and more efficient methodologies.

 I was a mathlete in school where I competed in tournaments and won prizes. That really inspired me and I developed a passion for math and technology. Since then, I continue to carry that passion and hope to use it to improve the world.
