Tools I work with

Flutter Dart Swift Kotlin Firebase Laravel Node.js Git

Three platforms, one standard.

Most of the work is Flutter. When a product needs the platform itself, I build native.

Flutter

Flutter

Primary lane

Riverpod, BLoC and GetX on Clean Architecture with feature-first DDD, so a codebase still makes sense two years in. Real-time layers on WebSocket, WebRTC and VoIP when a product needs them, up to end-to-end encrypted messaging on the Matrix protocol. AI wired in where it removes manual work rather than as a bullet point.

Where I have shipped

Jan 2024 to Present

Mobile Developer

Upwork, international clients

Five-plus projects for clients in Australia, Austria and Malaysia, including Remembli, Lawan, CashIO and Overtory. 95%+ positive feedback, delivered around 20% ahead of agreed timelines, and 30% better app performance from GetX and BLoC work on data-heavy screens.

Jan 2026 to Present

Founder and Fullstack Developer

ArtaCode

Founded a mobile product studio and shipped its first app single-handed. Notery went from an unmet need to a Google Play listing with no hand-off in between: the problem, the UX, the architecture, the whole codebase, the launch and the support after it. Clean Architecture with a feature-first structure and Riverpod.

Jan 2026 to Aug 2026

Flutter Mobile Developer

Private Company

Two client products. One a rewards platform where people take part in campaigns and get paid for them, with an AI system reviewing submissions automatically instead of a person checking each one. The other a secure messenger with end-to-end encryption, plus voice and video calling. Both on Clean Architecture with DDD, a feature-first structure and BLoC or GetX for state.

Mar 2023 to Dec 2025

Flutter Mobile Developer

Digital Sekuriti Indonesia

Led Flutter development on three live products: AI-Care, Callink and Rumah Berkat, all shipped to both the Play Store and the App Store. Built Callink's real-time chat layer on WebSocket over a DDD codebase, worth a 30% gain in team communication efficiency on internal metrics, and rolled FCM push across all three.

Jul 2022 to Mar 2023

Mobile and Web Developer

PT HKteknologi

Shipped Amal Ibadah and Booking Tempat in Flutter to iOS and Android on an MVC structure, with Laravel backends and REST integration for kolaborasi and bcomss.id.

How I build

Four years building mobile apps, most of it in Flutter, with Laravel behind it when a product needs its own backend. Everything goes on Clean Architecture with a feature-first structure, so what you own at the end is a codebase another developer can pick up without a rewrite.

The work I take on tends to be the part that is 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.

I have also shipped a product alone, start to finish. 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. A brief does not have to be finished before I can start.
