Flutter developer, 4+ years.
I build mobile apps end to end, from architecture through to the Play Store and App Store.

Based in Yogyakarta, working remote. Right now I am building an end-to-end encrypted messenger on the Matrix protocol at PT Aksa Digital Group, and running ArtaCode, my own mobile product studio, whose first app is live on Google Play.
Architecture that survives handover. Clean Architecture with Domain-Driven Design and a feature-first structure. The codebase you get back is one another developer can pick up without a rewrite.
The parts that are hard to fake. Real-time messaging over WebSocket. Voice and video on WebRTC and VoIP. End-to-end encryption on the Matrix protocol. AI wired into a flow where it replaces manual review instead of sitting in a demo.
The whole lifecycle. Notery went from an idea to a Google Play listing with no hand-off in between: research, UX, architecture, the build, the launch, and the support after it.
| Project | What it is |
|---|---|
| Notery | Private shared notes, calendar and reminders for couples. Designed, built and launched solo. Live on Google Play |
| AMOR | End-to-end encrypted messenger on the Matrix protocol, with voice and video over WebRTC |
| Dabtive Campaign | Social campaign marketplace where an AI validates the submission proof instead of a reviewer |
| AI-Care | AI symptom self-checker paired with real-time clinician consultations. 1,000+ active users |
| Callink | Team messaging with channels, threads and calls, on WebSocket over a DDD codebase |
14+ apps shipped across health, messaging, social and public-sector work. Freelance clients in Australia, Austria and Malaysia: 95%+ positive feedback, delivered around 20% ahead of timeline.

25 of my 49 language-tagged public repos are Dart, ahead of everything else by a wide margin. Most of the interesting work lives in private client repos, so the portfolio is the fuller picture.
Open to freelance and contract work.
