A little bit about myself, I am originally from Mongolia, where I earned bachelor’s degree in Printing Engineering. I came to the United States 2015 to pursue the American dream of having the opportunity to achieve success through hard work and learning from failures. 2018 was the start of a new beginning, as I started the Associate of Applied Sciences degree for Information System Technology. I graduated Summa Cum Laude in 2021.

Two months after my graduation, I enrolled in a Java Web Development bootcamp, online. I gained real life “hands-on experience”. The bootcamp provided me with the chance to utilize Java Spring Boot framework. I was able to build five major spring web applications.

Puzzles, the unsolved, building, and creating have always been my “jam”. Finding solutions and learning provides me with a great sense of accomplishment and satisfaction. Coding, in a sense, is just the ultimate, infinite puzzle! My passion for coding is derived from what makes me up as an individual, and it's what drove me to choose a career in IT as a software engineer.
