Frontend developer based in Indonesia, 8+ years building React, Next.js, and Astro projects. Most of my work is for SaaS companies, e-commerce stores, and B2B web apps.

If something in the spec or design doesn't make sense, I bring it up before we start instead of building the wrong thing in silence. I'm comfortable working async, joining standups, and following whatever conventions you already have set in your repo.
