I'm a machine learning engineer, photographer, and sketcher, currently based in Berlin, Germany.

I currently focus on building tools that evaluate AI agents, having previously worked across food delivery, payments, and social media domains throughout Southeast Asia and Europe.

Over 8+ years, I've built machine learning systems from the ground up—from initial requirements gathering to production deployment. My work spans risk and fraud detection, natural language processing, and customer analytics, now extending into AI agent evaluation and testing methodologies.

I approach problems with a product mindset, balancing technical excellence with user needs and business impact.

I've also been involved in community outreach around inclusive tech communities by co-hosting Kartini Teknologi podcast, serving as a Google Developer Expert in Machine Learning, and volunteering with organizations like ReDI School and Aidha.
