Hi, I'm Rahmat
Software Engineer
building with AI & Cloud.
6+ years in the automotive industry — turning data, embedded systems, cloud and generative AI into reliable products. Driven by 自走力 and チームワーク.
Engineer in Japan. Learner by default.
Indonesian software engineer with ~6 years in the automotive industry — combining hands-on engineering with a constant appetite for new tools and systems.
I work across Python, MATLAB, C/C++, JavaScript, AWS, and modern AI systems — with a strong interest in cloud computing, RAG, generative AI, and scalable web applications.
My philosophy is simple: learn by building. I investigate problems independently before consulting seniors, contribute to teams while continuously leveling up, and care deeply about communication and continuous improvement.
