Hello, I'mIvan Ramadhan
Arifin
Fullstack Developer
Mechanical engineer turned developer. I debug systems — whether that's heavy machinery or distributed APIs.
The story so far
I started as a Mechanical Engineerat ITS — designing systems, analyzing failures, running numbers. When I switched to software, I didn't leave that mindset behind.
“Understand the system, find the failure point, fix it cleanly. No magic — just methodology.”
After Hacktiv8 and years at Loyal.id, I've shipped 10+ apps to the Play Store and built internal tooling that actually gets used.
