I’m starting a new Android-only mobile product and I want it built in Flutter from day one. Because no server-side logic exists yet, the first milestone will be to design and code an entirely new RESTful (or GraphQL, if you prefer) API layer. I’m comfortable with either PHP (Laravel/Lumen) or Node.js (Express/Nest) as long as the endpoints are clean, secure, and documented. Core requirements • Flutter code that compiles and runs smoothly on Android devices • Fresh APIs with robust data storage behind them (MySQL or PostgreSQL are fine) • Clear documentation so future features can plug in without rewrites Typical tasks you can expect after the first release range from adding new database entities and refining queries to implementing extra Flutter screens and hooking them to the API, so think of this as project-based but long-term. Acceptance for each deliverable – Flutter project pushed to Git with clear commit history – API repository with test coverage and README covering environment setup, routes, and example requests – SQL schema or migration files version-controlled alongside the backend – Postman / Insomnia collection or Swagger/OpenAPI spec showing every endpoint If you enjoy building green-field systems where you own both the mobile front and the server logic, this should be a smooth fit.

Hi, I can build your Android-only product from scratch in Flutter, with a clean and scalable architecture from day one. For the backend, I’d recommend Node.js with NestJS to create secure, modular, and well-documented REST APIs. I’ll build the database layer using PostgreSQL, including version-controlled migrations and optimized queries. The Flutter app will be fully integrated with the APIs and tested across Android devices for smooth performance. You’ll receive Git repositories with clean commits, backend test coverage, README documentation, and environment setup instructions. I’ll also provide a complete Swagger/OpenAPI specification or Postman collection covering every endpoint and example request. After the initial release, we can continue adding features, APIs, database entities, and Flutter screens as the product evolves. Best, Rahul

Hi, I can start your Android product in Flutter and build a fresh REST API in Laravel with MySQL. The API will use Sanctum auth, versioned routes, request validation and API resources, documented with Swagger and a Postman collection so future features plug in without rewrites. On Flutter I use a clean layered structure (data, domain, UI) so new entities and screens stay simple to add. Each deliverable will be pushed to Git with clear commits and a README. I am fine with the long-term project-based model for new tables, query tuning and extra screens. Do you have designs ready? Regards, Harsh Thoriya

First thing I'd lock down is the OpenAPI spec, every endpoint, request and response shape, auth flow, before a single Flutter screen gets built. That's what actually makes "future features plug in without rewrites" true, the app codes against a contract instead of whatever the backend returns that week. With the spec signed off, the API comes next, Laravel or Node/Express on MySQL or Postgres, versioned migrations from the first commit, test coverage on the core routes, Postman/Swagger kept as a living doc rather than written up after the fact. Flutter comes last and consumes the finished contract, so new screens don't touch network code directly. 65,000 INR over 6 days, paid in steps so nothing's released before it's checked: M1: API contract, schema, migrations, Rs 21,450, 2d. M2: Backend build, auth, endpoints, tests, Rs 26,000, 2.5d. M3: Flutter app on the API, Postman docs, README, Rs 17,550, 1.5d. That number's off the brief as posted, the real swing factor is how deep the auth needs to go, plain email and password or social logins too, so I'd rather pin that down before calling it final. Send over any wireframes or auth details you've got and I'll start with M1, the contract and schema, so you can see the API's shape before anything else gets built on it.

You want an Android-only product built in Flutter, with no existing server, so the first piece of work is a new REST API and a SQL database behind it. After that, Flutter screens should plug into those endpoints without rewrites. Acceptance is a Git history, API tests and a README, versioned SQL migrations, and a Postman collection or OpenAPI spec. I would build the backend in Node.js with NestJS and PostgreSQL. Auth, validation, and documented REST routes would come first, with Swagger generated from the code. The Flutter app would use a feature-based structure, a typed API client, and secure token storage on Android. Milestones I suggest: 1. Schema, auth, and core endpoints with tests and OpenAPI docs. 2. Flutter screens for the agreed flows, connected to the API. 3. Integration testing and a signed Android release build. Could you share the user flows that must ship in the first release, and whether you already have a data model or wireframes I should follow?

Dear Client, I read "Flutter Android App & Backend APIs" carefully and understand you want a single Flutter codebase that runs smoothly on both Android and iOS. My hands-on experience with PHP, Mobile App Development, Android, MySQL, Node.js, Backend Development, Flutter, API Development aligns directly with what you need. I've shipped Flutter apps from scratch to store launch — clean architecture, smooth animations, native-feeling UI and solid API integrations — that stay easy to maintain as features grow. A few quick questions to get us started: 1. Do you need Android, iOS, or both from day one? 2. Are UI designs ready, or should I design the screens as well? 3. Is there an existing backend/API, or should I build that too? Thanks & Regards, Deepak

Hi, I’m interested in building this greenfield Android product where both the Flutter application and backend API can be designed properly from day one. I can build the Flutter app with a clean, maintainable architecture and develop the complete backend using Laravel or NestJS, with PostgreSQL/MySQL depending on the project requirements. For the API, I’ll structure authentication, validation, database models, business logic and error handling cleanly so future entities and features can be added without rewriting the foundation. I’ll provide version-controlled migrations/schema, automated API tests, clear README documentation, and a complete Swagger/OpenAPI or Postman collection with example requests. The Flutter project will also be maintained with a clear separation between UI, state management, API integration and business logic for easier long-term development. I’m comfortable taking ownership of both sides and continuing with future screens, database changes, queries and API integrations as the product grows. I can start with the architecture and first milestone, then build incrementally with meaningful Git commits and testable deliverables. Best Regards, Jitendra Sharma
