I build AI systems that have to work outside a notebook—real-time voice agents on robots, edge inference, reasoning models, and small products people can actually use.
A few things I've built:
- 🧠 Qwen3.5-4B GRPO — post-training with verifiable rewards that lifted GSM8K pass@1 from 85.4% to 92.4%
- 🔎 Deepfake Detection — an explainable image-forensics toolkit combining a learned classifier with ELA, FFT, noise, and EXIF signals
- 📦 RAGBox — a local-first RAG command-line tool, packaged for
pip install ragbox - 📉 Transformer Crypto — eleven experiments asking whether transformers can predict markets; the honest answer was more interesting than the optimistic one
- 🧰 ToolsGratis — 15+ Indonesian-first utilities that process files entirely in the browser
Previously, I shipped a real-time voice agent with ~20 tools across 10+ tour-guide robots, and brought speech and vision models onto edge hardware. These days I'm exploring RL post-training, auditable multimodal systems, and software that earns a permanent browser tab.

I write up the useful parts—including the experiments that fail—on Substack.
