About me
I've been selling online on my own since junior high, with no one helping me. It taught me independence, discipline, and ownership of my results. Around the same time I started coding through robotics competitions. My team won 2nd place in the Bali Provincial Sumobot competition in 2019. In high school I moved into web development and won 3rd place in the High School Web Design Competition at ITCC 2022, Udayana University. Now I study Computer Science at BINUS and work as the Frontend Developer and UI/UX Designer of StairsLife, a student freelance platform showcased at Computer Science Festival 2026. Outside campus I built and run Pica Chocolate Bali, including its website and online stores on three marketplaces. This taught me to write code that real users depend on. I enjoy working in teams with clear goals and clear roles. I'm not the smartest person in the room, but I'm ready to keep learning until I am.
