Summary

Since my second year of junior high school, I have explored various technological domains, including mobile, web development (including frontend and backend), security, and machine learning. My curiosity has consistently driven me to not only embrace challenges but also to create impactful solutions that influence others. Upholding a professional standard without compromise in any IT domain is my motto, and I'm always keen to broaden my horizons in diverse fields. My journey has been marked by diverse internships, offering me practical experience across a wide range of areas.


I have been actively involved in initiating numerous teams and projects, accumulating substantial project management experience. At university, I further honed my leadership skills by spearheading the establishment of the Web team within the University Festival Committee.
