AI Engineer · Jakarta, Indonesia
AI that answers calls, chats and orders
I build the AI workers behind the repetitive jobs: voice agents that hold a real phone conversation in under a second, chatbots grounded in your own data, and automation that runs an e-commerce back office overnight. Shipped to production, deployed on your own servers.

About Me
AI Engineer & Full Stack Developer
I'm an AI engineer based in Jakarta, Indonesia. I build conversational and automation systems that go into production and stay there: voice agents, chatbots grounded in real business data, and the back-end infrastructure underneath them.
At HERA I built agentic AI from the ground up — a low-latency voice platform with real-time bidirectional audio, and an AI video generation platform. Before that, enterprise ERP and e-commerce automation. The through-line is the same: systems that carry real load, deployed on infrastructure the client owns.
