Device-oriented workflows
My mobile diagnostic work has involved features such as camera, audio/video, geolocation, NFC, BLE, biometrics, sensors and voice/TTS where supported by the target device and project requirements.

React Native Developer for Production Mobile Apps
I’m Amin Asadi Vosta (AminVost). My React Native work includes mobile diagnostic flows, hardware- and sensor-oriented features, backend communication and the practical debugging needed when an application depends on real devices rather than only standard UI screens.

Mobile engineering
React Native beyond basic screens.
I work on the application layer as well as the integrations that make mobile products useful: device APIs, native behavior, communication, permissions and production debugging.
React Native + native integration
When a React Native library is not enough, I’m comfortable working around native Android/iOS behavior, diagnosing compatibility problems and connecting JavaScript flows to device capabilities or companion tooling.
WebSocket and backend communication
Mobile applications often need more than local UI state. I’ve worked with WebSocket-style status/command flows, REST APIs, authentication and companion desktop/server services as part of diagnostic and cross-platform systems.
Production debugging
Real-device development means handling hardware differences, unsupported capabilities, permissions and edge cases. I treat those behaviors as part of the product, with explicit supported/not-supported flows and careful fallback handling.
Mobile projects
React Native and mobile case studies.
Projects that show hands-on mobile development rather than generic technology keywords.
RapidMobileDiag is the primary React Native/native-focused case study. Pantomin, Shab and the competition platform demonstrate installable PWA and mobile-first product delivery; they are not presented as native applications.
RapidMobileDiag
Mobile-device diagnostic application built with React Native for iOS and Android, covering device-test workflows and communication with companion services/tooling.
Pantomin pantomim.aminvost.ir/
Persian mobile-first charades game delivered as a PWA with local-first behavior, offline tolerance and production VPS deployment.
Competition Management Platform game.aminvost.ir/
General-purpose tournament and competition management platform for digital games, FC/PS5 events and in-person board-game competitions.
Shab — Persian Mafia Game

TodoList Mobile App
Simple mobile application for personal to-do management, preserved as an early mobile-development project.
Related stack
Mobile work connected to the rest of the system.
Full-stack context
I also work across Next.js, React, PHP, APIs, WebSocket, Linux and production infrastructure. That matters when the mobile app is only one client inside a larger product workflow.
Cross-platform perspective
My broader experience includes PWAs and Electron applications, so I’m used to deciding which logic belongs in the client, what should be shared with backend services and where platform-specific behavior is unavoidable.
