I'm Eric, a Flutter developer at PT Semesta Arus Teknologi who also builds the web side — Next.js or Svelte up front, FastAPI or Laravel behind. Nine apps shipped so far, from attendance for Samarinda's civil servants to booking traditional artists through Rudaya.

03 — Services
A mobile app, a web app or the API behind them — from first sketch to launch, in code the next developer can read.
Track down bugs and crashes, find what makes a screen slow, and get the app feeling quick again.
Pick up an existing Flutter, web or backend project, tidy what slows the team down, and keep shipping features.

04 — About
Komang Eric Widhi Antara — Flutter developer at PT Semesta Arus Teknologi. I'm curious by default, especially about tech, and I like problems that sit close to everyday life.
The project I'm proudest of is Rudaya, an app that helps people book traditional artists anywhere in Indonesia. It's the kind of work I want more of: well made, and genuinely useful to a lot of people.
