AI Engineer in Semarang, Indonesia. I build AI systems from the infrastructure and service architecture side: model gateways, request routing, failure handling, and tool orchestration.
I am studying pure mathematics at Universitas Negeri Semarang. The habit of working from definitions and proofs carried over, so I read a model's assumptions and limits before putting it into service.
