--:-- in Indonesia

hey, I'm Photo of YarZ YarZ.

I build backends from Indonesia. Two AI products of mine run on them, and I take on client work too: scrapers, private APIs, web apps with payments.

What I'm up to

The longer version

grab a coffee

Most of my work starts from one belief: if data shows up on a screen, there's a way to get to it. Sometimes that means a scraper. When I can, it means the private API behind the web or Android app, because an API breaks less often than a page does.

For clients, that usually grows into a whole system. The scraper or API client, a job queue and workers behind it, webhooks that confirm payments, and a Next.js app on top.

Renderly Studio is my own take on it, built for Indonesian creators. Paying for AI image tools usually means a foreign card and a dollar price. Renderly takes Rupiah over QRIS and only charges when the image actually comes back. MotionFly is the video side: one photo and one motion clip in, an HD video out.

These days I split my time between those two and client work. I care about privacy, I keep my interfaces quiet, and I like animals.

stuff I can help with
  • Scrapers and automationScheduled jobs that keep working when the site changes.
  • Private API integrationsAn app has no public API? I map the one it uses.
  • Backends and infraGateways, queues and workers on a VPS or Cloudflare.
  • Full-stack appsNext.js, from sign-in to payments.
