About
I work across product, engineering, and growth, on purpose.
I started in software engineering and design, and I was an early voice in the Indonesian Flutter community. Over time the work moved from writing code to building companies, teams, and growth systems that keep users around.
Today I run Kreatorku Indonesia and ship AI-native ventures. The AI pivot cut our development time by 10x and our infrastructure cost by 90%, while reliability went up.
The best technology is still useless without a plan to keep users engaged, so I keep my hands in growth engineering, customer experience, and the numbers that prove the work.
