Hi, I'm Ariel Yosua Hasibuan

I am a Computer Science student at Pertamina University and a tech enthusiast passionate about exploring how technology can solve real-world problems.

My current learning focus is on diving deep into Data Science & Analytics, Machine Learning, and Mobile Programming, with a growing interest in the field of Cybersecurity. I enjoy the process of transforming raw data into useful predictive models, as well as building intuitive and functional mobile applications.


🚀 Featured Projects

  • DompetKu - Financial Tracker

    • A cross-platform personal finance tracker app built with Flutter and Firebase. Features include real-time data synchronization, interactive charts, and full CRUD (Create, Read, Update, Delete) functionality.
  • Waste Classification Using CNN

    • Built an image classification model using CNN (MobileNetV2 and DenseNet121) to categorize waste types from the TrashNet dataset. Applied data augmentation, class weighting, and fine-tuning to improve accuracy, especially for minority classes like “trash”.
