Informatics Engineering Student @ Institut Teknologi Bandung
Hey, I'm Peter.
Wongsoredjo, not Parker. Your friendly neighborhood coder, mainly focused on Data, AI, and Software Engineering.
I love cool things, and coding turned out to be the best way to build whatever's living in my head. That's how I ended up caring about data engineering, AI, and software engineering.
