About
I was born and raised in Medan, I'm Karo, and I now live in Tangerang. I graduated in Information Technology from Telkom University in 2025.
Before focusing on software engineering I came at it from two directions: UI/UX design (two competition wins) and cybersecurity (AWS and Palo Alto Networks certifications). Both still show in how I work — clear interfaces, and systems that are hard to break into.
