About Me

Hi! I am an fresh graduate physics student at Gadjah Mada University. I am a highly motivated and energetic individual who thrives in a team- oriented environment.

My insatiable curiosity about the world of data is a driving force in my academic pursuits, as I believe that data can unveil a wealth of insightful information that we may not have even considered before.

Despite coming from a non-IT background, my enthusiasm for the world of data is unparalleled. I am particularly drawn to the field of machine learning, recognizing its potential to unlock new possibilities and transform how I understand and interpret data. I am eager to contribute to the advancements of machine learning and its potential to revolutionize various industries.
