I am an experienced, results-oriented consultant with an engineering background who has advised over 15 companies across the mining, property, and gas industries, including PT. Freeport Indonesia, PT. Angkasapura Properti, and PT. Brantas Abipraya.

I apply quantitative analysis and logical reasoning to diagnose complex business problems and deliver actionable solutions under tight deadlines, managing multiple projects with responsibility and organization.

I specialize in AI training and data work—data annotation, content creation, and quality assurance—paired with strong technical and professional writing skills that make me well-suited to improve AI models and documentation.

I am bilingual in Indonesian and English with conversational Japanese, and I hold a Bachelor of Engineering from Institut Teknologi Nasional Yogyakarta. I seek roles where clear communication, collaborative teams, and measurable impact are valued.
