React Native & Spring Boot App

@crtvecode

When developing a cross-platform app, the real challenge lies in creating a cohesive user experiance that feels native on both iOS and Android while maintaining a single codebase. To mitigate any risks during development, I'll work in a controlled environment, making sure no disruption to your existing systems. Planning phases: Initial setup: Create a private repository for React Native and Spring Boot. UI development: Build screens, navigation, and state management for both platforms. API integration: Develop secure REST API endpoints and connect them to the mobile app. Testing and deployment: Compile builds and conduct thorough testing before final delivery. What specific features do you envision for the initial sprint that we should prioritise? Rajavel

@Abror86

Hello Hope you are doing well "Build Cross-Platform Mobile Application" - You want a cross-platform app built with React Native and Spring Boot REST APIs securely. I can set up React Native screens, navigation, state management alongside Spring Boot models, services, endpoints, authentication, and database integration following clean architecture principles throughout development. I will configure shared iOS and Android builds, test REST endpoints, maintain Git commits, provide deployment scripts, documentation, and sprint demos for smooth handover and deployment. Would you prefer PostgreSQL or MySQL for the Spring Boot backend database? Looking forward to working with you.

@lytrungtin

Your React Native & Spring Boot App brief reads clearly. I work with Java and JavaScript every week, and I would keep the delivery steps simple. How I would handle it: • Clear checkpoints so you can see progress as it happens • Java handled end to end: setup, implementation, then a short handover • Test the important paths before calling anything done The first step stays small so you see something working quickly, then we build on it. Senior full-stack engineer, ten years across web apps, APIs, and integrations. Milestones: 1) confirm the plan, 2) implement the app, 3) verify and hand over. Quick question: do you already have Java work in place, or should I set that up too? Cheers, Tin

@w3loop

Hi, I understand you need a cross-platform React Native application with a secure Spring Boot REST API, shared codebase for iOS/Android, Git-based development, documentation, and sprint-wise demos. I’m a Senior Full Stack Developer with 8+ years of experience in web application development, including 2+ years with React, Node.js, Laravel, REST APIs, authentication, database design, and third-party API/payment integrations. I can handle the React Native application structure, navigation, API integration, state management, and backend/API architecture with a clean and scalable approach. I’ll keep the code well-structured, maintainable, properly documented, and ensure both Android and iOS builds are tested from the same repository. I’m available to start immediately and can discuss the product requirements and sprint plan before development. Regards, TechAvinya

@marvind18

You need one developer who can own both the React Native experience and the Spring Boot API, while keeping iOS and Android behavior consistent from a shared codebase. I have 9+ years of full-stack experience with React, React Native, Java Spring Boot, REST APIs, PostgreSQL, authentication, and production deployment. At Ecube Labs, I built responsive React-based interfaces, and my backend work includes Java services and database-driven business workflows. I’ll structure the mobile app with reusable components, typed API services, predictable state management, platform-aware navigation, and isolated native configuration. The Spring Boot backend will use clear controller, service, and persistence layers with validation, role-based security, migrations, error handling, API documentation, and endpoint tests. I’ll keep commits focused, document local setup and environment variables, and provide reproducible build and deployment scripts. The feature list is currently too broad to estimate responsibly. Which user roles and core workflows must the first release include, and do you already have wireframes, database preferences, and authentication requirements?

@Visharaa2024

Hi, The React Native side is a strong match, and I’d structure the project around a shared TypeScript codebase for iOS/Android with clear separation between screens, navigation, state and API services. Since the product requirements are still being refined, I’d keep the architecture modular so new features can be introduced sprint by sprint without restructuring the application. For the backend, I’d normally use Node.js/Express with a documented REST API, validation, secure authentication and a database layer, with tested endpoints and deployment configuration maintained alongside the mobile project. Our strengths are React Native, TypeScript, REST APIs, Node.js, PostgreSQL, authentication and production-oriented application architecture. We can also work with regular Git commits, sprint demos and concise technical documentation. One point to clarify: is Spring Boot mandatory, or would Node.js/Express be acceptable for the backend? If this aligns with your requirements, we can proceed with the technical setup and first sprint scope. Best regards, Deepak.

@nakabirik

Hello, I have read your project requirement description carfully! A React Native + Spring Boot app needs the mobile state and REST contract designed together so iOS and Android do not drift from the backend. I’d structure the React Native app with reusable screens, navigation, and predictable state management, while Spring Boot handles validation, service logic, persistence, and documented REST endpoints. I’ll keep DTOs and API contracts explicit, add endpoint tests, configure both mobile build targets from one repository, and maintain clear Git commits and setup notes. I’ve worked across mobile apps, Java/REST APIs, backend integrations, and production services where clean API boundaries mattered. Can you share the initial screen list and data model so I can map the first sprint into the React Native and Spring Boot structure? Looking forward to working with you. Muheebwa

@indreshpnk

Hello, I understand you need a cross-platform mobile application built with React Native and a robust Java Spring Boot backend. The goal is to deliver a native-feeling iOS/Android app with a secure, well-documented REST API and a clean shared codebase. Here’s what I can provide: React Native screens, navigation, state management, and iOS/Android builds Spring Boot REST APIs, data models, authentication, and clean backend architecture Git-based development, API testing, README documentation, and deployment setup I bring over 4+ years of experience in Java, JavaScript, React, Node.js, Django, REST APIs, SQL/NoSQL databases, and full-stack development. I’ve built API-driven applications with authentication, role-based access, database integration, and responsive frontend interfaces, with a strong focus on maintainable architecture. Just to clarify a few things: Do you already have the initial UI designs or should the screens be designed during the first sprint? Which database and authentication approach do you prefer for the Spring Boot backend? Please come to the chat box to discuss more about your project. Best regards Indresh Kushwaha

Balancing native feel with a shared codebase often trips on heavy bridge calls that slow UI updates. I’ll set up a monorepo and init React Native with React Navigation and Redux Toolkit. Then I’ll create a Spring Boot service that exposes DTOs through a REST API protected by JWT. A common mistake is sending large JSON payloads, which forces the bridge to marshal data and slows the UI on both iOS and Android. You’ll see snappy screens and reliable endpoints, so each sprint demo will showcase a fully native feel with clean API contracts.

@amit719

Hi, I can handle the complete React Native + Java Spring Boot development workflow, from project architecture through working iOS and Android builds and a secure REST API. I’ll set up the React Native app with responsive native-feeling UI, navigation, state management, reusable components, and reliable API integration. On the backend, I’ll build a clean Spring Boot architecture with well-structured data models, secure REST endpoints, validation, error handling, and tested APIs. I’ll maintain everything in a single Git repository with regular commits, clear README documentation, setup/API instructions, and a basic deployment script. I’ll also verify both platform builds and demo progress at each sprint milestone. I’m comfortable working iteratively while the final feature set is refined, and can start with sprint planning to establish the architecture and development roadmap. Thanks Amit
