Work

Every project, and what changed.

The reworks

• KlasifikasiSentimenTwitterNaïve Bayes hate-speech classifier for Twitter/X comments, published in the Journal of Informatics and Science Media (JISMEDIA).
• BreastInsightA CNN classifier for breast ultrasound images, rebuilt after finding the training data was silently contaminated with segmentation masks.
• BankruptWatchA bankruptcy risk classifier rebuilt after discovering the original 'accuracy' claim didn't match what the code actually did.
• LaundryGISA GIS dashboard for laundry shop locations — every page had been pointing at a dead localhost iframe.
• IndoNewsClassifierA text classifier for Indonesian-language news articles, deployed as a live Streamlit demo.
• ShortestPathAppA Java desktop application for visualizing shortest-path algorithms, fixed and verified with a real JDK.
