Side projects and public repositories.
An agentic studio that turns small sellers' real product photos into on-brand campaign images: a brief, an art director, a brand guardian critique loop and a copywriter, with text and logos composited in code (never model-rendered) and checks against Indonesian marketplace rules. Built solo across 15 feature specs, with a GitHub Copilot coding agent under my direction.
An AI calorie tracker: log a meal by text or photo, including Indonesian food, and get a vision-model nutrition estimate with daily to monthly summaries, per-user rate limits and a clearly labelled fallback.
A self-hosted dashboard for my AI coding sessions (repos, tools, costs and insights), built in one day by an AI agent while I owned the product and the review.
A multi-agent jury that stress-tests my own product ideas: ten AI juror roles, a devil's advocate and a meta-judge over eight rounds, with blindness rules, fresh research and peer challenges.
Exam simulators and focus packs I built to prepare for Microsoft and GitHub exams: a GH-600 trainer with 80 original scenario questions and explanations, and an AI-103 simulator with a timer and domain breakdown.
My BSc thesis: crawls posts about a university, predicts sentiment with a fine-tuned IndoBERT and tracks it in a Django dashboard, with the model public on Hugging Face.
Aspect-based sentiment on app-store reviews of four Indonesian e-wallets, the selection-phase model of a data competition my team won, later co-authored as a paper.
A group project: a Streamlit app that maximizes returns under sector and diversification limits using SLSQP.
A Next.js tracker for crypto holdings on live market data.
An interactive map that visualizes clustered real estate listings with filters.
