About

During my college years, I was a diligent music student pushing myself to grow - I practiced, performed, and placed in numerous competitions. Being a music student was challenging, but I had an ardent interest in personal growth and knowledge that led me to push my horizons, and start exploring my passion for the technology field.

In 2020, I began to learn to code. I learned the basics of HTML, CSS, JavaScript, and React, and found my talent in tech. I first put my skills to use developing a comprehensive, fully featured and functional website for a local company - there I learned how to implement my knowledge to solve real-world business challenges.

I decided to explore more avenues to learn as much as possible, making project after project to hone my skills. After joining larger development teams like in the National Data Police Coalition, I grew more and more as a developer not only singularly, but with experience working in a professional team setting.

After 4 years, I continue to work on exciting projects like TuneSplit while I utilize my extensive coding knowledge at Data Annotation, where I am able to push AI models to the limit while also expanding my own knowledge. Every day I learn something new.

Beyond tackling a new project, I enjoy activities that challenge both my mind and body, from staying active through sports to appreciating music on the couch with my cats.
