"Si Oyen" — an Indonesian nickname for orange cats.
Chaotic, curious, and sometimes surprisingly smart.

Who is Si Oyen?

🟧

The Name

c-oyen comes from "Si Oyen" — the Indonesian nickname for orange cats (kucing oren). One braincell, infinite curiosity, suspiciously capable.

💻

What I Do

Passionate about software engineering, web technologies, and developer tooling. I enjoy experimenting with new stacks, workflows, and infrastructure setups.

🔧

How I Work

I learn by doing — building random things, breaking stuff responsibly, and constantly refining both technical and problem-solving skills.

☕

Fuel

Powered by curiosity, coffee, and orange-cat energy. Orange cats are known for sharing one braincell — sometimes I get scheduled access to it while coding.
