Đorđe Stanišić

Flutter Software Engineer

I build production mobile apps for Android, iOS, and the web — from architecture to the store listing.

About

I’m a Flutter engineer with 5+ years of mobile experience, focused on shipping real products — white-label platforms, reusable architectures, and apps that make it to the App Store and Google Play. I care about clean structure, the last 10% of polish, and taking an idea all the way to users.

Right now I’m a Software Engineer & Product Developer at Omniway, where I build and launch apps end-to-end: architecture, features, payments, analytics, and the distribution around them. Recent work includes Povratak na selo (6,000+ users), WriteReal, an AI text humanizer, and PrayBefore, a live prayer and Bible app.

Before that I built fintech, ERP, retail, and fitness products at Crealogix and Crystal Pigeon — including a white-label banking app for a Swiss client and store software used by tens of thousands of people.

    Flutter Software Engineer · Crealogix

    MobileXApp (DBAN) — white-label fintech

    Built a white-label fintech app from the ground up for a Swiss banking client in a 10-person team. Connected Flutter UI to backend services and shared libraries for device binding, configuration, and theming — so new banking clients could be onboarded without rebuilding the product. Worked in a layered architecture (pages, widgets, atoms, molecules, notifiers, providers) with developers, backend, design, and QA.

    Karen — data consolidation white-label app

    Led Android and iOS development in a four-person team, turning an existing web app into a cross-platform white-label product that supported three client apps. Set up GitHub Actions CI/CD for all three builds, added Firebase Crashlytics and push notifications, and used Riverpod for state across the variants.
