Product Engineer · Founder · Applied-AI Builder
"Beyond the code, I build experiences."
Muhammad Luthfi Arifin is a Product Engineer and Applied-AI builder based in Indonesia with 5+ years shipping scalable, mobile-first, full-stack products. I currently build at Tech in Asia and founded byShape Studio — and today I'm focused on Applied AI: harnessing LLMs, Retrieval-Augmented Generation (RAG), and agentic workflows to ship practical tools that solve real problems.
