01 - About
Curious by default, shipping by habit.
I like building AI systems that move from experiments into real use: fine-tuning small models that run on a Raspberry Pi, building RAG pipelines that need reliable answers, and training vision systems for robot soccer.
Recent work includes an offline BISINDO translator for the Tuli community (KawanIsyarat), a multimodal retail-analytics platform that won DATATHON 2025 (TRACKO), and a lightweight Indonesian text-to-speech model (NusaVoice).
Outside the terminal, I hike, play football, and lead Gadjah Mada Robotic Team - FUKURO, which qualified for RoboCup 2026 in Incheon, South Korea.
