About Me
I'm Raihan, an ai expert & cloud engineer based in Jakarta, Indonesia. I specialize in building production-grade LLM platforms, AI agents, and scalable ML infrastructure.
With a background in Mathematics from ITB and hands-on experience deploying large-scale AI systems, I bridge the gap between cutting-edge AI research and real-world production deployments.
