What I'm looking for

I’m immediately available and want to build production Flutter apps using Clean Architecture, Riverpod, offline-first syncing, and native integrations. I enjoy partnering with backend teams on Spring Boot/Node APIs and shipping polished, maintainable enterprise features.

I’m a Flutter & mobile engineer with production experience since September 2024, having built and shipped three concurrent enterprise-grade systems end-to-end. I architect with Clean Architecture and SOLID, and I’ve delivered a metadata-driven form engine that renders 90+ complex forms dynamically—later extracted into the open-source rj form engine package. I also built centralized, type-safe navigation with GoRouter and implemented JWT-based authentication with dynamic role-based access control (RBAC).

My focus is making real-world apps reliable under constraints: I engineered an offline-first data layer using Hive caching (SWR/TTL) plus conflict-resolution strategies (LWW, CRDTs), and I delivered a Windows + Android POS kiosk system integrating Win32 APIs and ESC/POS thermal printers via Flutter Method Channels. I collaborate directly with backend teams on Spring Boot REST API contracts and contribute to Node.js services, and I’ve shipped a solo Play Store app with 50K+ downloads.
