About Me
Two roles, one shared principle
I've been building for the web since 2019 — designing and maintaining more than 20 applications across domains, from hospital information systems and learning management systems, to government systems and ERP. But long before that, since 2013 I was already on the other side of the screen: supporting students as a lab assistant, and now working as a competency assessor and technology workshop facilitator.
To me, writing clean code and explaining complex concepts simply come from the same principle: clarity. My master's research at Universitas Gadjah Mada on programmer productivity analysis — published at an IEEE conference — grew from that same curiosity: how people work better, whether in front of a computer or in front of a classroom.
