Message

At Bank SMBC Indonesia, I lead design operations for six designers and three writers, supporting consistent quality and delivery across product squads. I also govern the web and mobile design system, auditing components and enforcing standards used across 15+ MVPs.

At Chamjo, where I’m Co-Founder, I helped grow the product to 125,000+ active users and 1.7M+ views. I led a web app revamp that drove approximately 115% growth in registered users while lowering the bounce rate.

I also own revenue growth across acquisition, free-to-Pro conversion, and retention, partnering with the CEO on pricing and subscription strategy. I lead Chamjo’s content pipeline and day-to-day operations across product, design, marketing, and business.

Earlier, at SUB1 Design Studio, I conducted competitive analysis, developed illustration systems in Figma, and ran usability tests. I’ve also taught and mentored UX design, including as a UI/UX Instructor at Inixindo.
