Professional Summary

Beginning with my path to fluency in Japanese, I have continually sought out difficult subjects to learn and master in an efficient manner. This mindset has given me the ability to grow rapidly in the fields of backend web development, blockchain contract development, Computer Graphics, and Machine Learning while also leading me to start a thriving private Japanese tutoring business that I ran solely.

My portfolio demonstrates my ability to learn difficult, brand new topics through hard work, smart thinking, and a calm mind in the face of an overwhelming amount of knowledge required to become proficient.
