Hi there, If client name is unnamed, then don't include client name on the proposal I’m a senior Flutter developer with deep hands-on experience in Clean Architecture and true Domain-Driven Design, aligned with the needs of your cross‑platform card-management app. I will refactor existing modules for a layered, testable architecture and deliver secure, scalable features (activation, balance fetch, transaction lists, in‑app notifications) while integrating REST/GraphQL APIs and robust local persistence. My approach emphasizes maintainable code, CI/CD readiness, unit/widget testing, and a data-driven domain model that supports rapid, reliable sprint delivery. I’m proficient with Riverpod and Bloc for state management and will ensure zero analyzer warnings as part of the refactor. My plan - Phase 1: Audit and refactor core modules to align with layered architecture and domain models, setting up thorough widget tests and unit tests. - Phase 2: Implement at least one end-to-end card feature per sprint with clear acceptance criteria and test coverage. - Phase 3: Integrate secure APIs (GraphQL/REST), local persistence, and CI-ready merge requests with concise domain documentation. - Collaboration: Overlapping Japan Standard Time hours, daily stand-ups, and a private Discord channel with weekly sprint calls; camera-on is noted as non-negotiable. Why me - strong Flutter/Dart expertise with practical experience in GraphQL and REST API integration, CI/CD pipelines, and secure data h

@rbtech1984

Hello, I’ve reviewed your Flutter card management app expansion. You need a senior developer to refactor with Clean Architecture & DDD, add secure card features, and deliver test-covered modules that compile cleanly on iOS and Android, aligned with Japan timezone collaboration. Services mentioned here based on project details ⚜ Refactoring to layered Clean Architecture ⚜ Strong Domain-Driven Design modeling ⚜ Card activation, balance & transaction flows ⚜ Secure REST/GraphQL integration ⚜ Riverpod/Bloc state management ⚜ Unit & widget test coverage per sprint ⚜ CI-ready PRs with clear documentation With 9+ years in mobile development, I’ve built fintech-style apps handling payments, APIs, and structured domain layers. I enjoy owning codebases and improving architecture step by step. My approach is to stabilize core modules first, enforce analyzer-zero policy, define aggregates/use-cases clearly, then ship one end-to-end feature each sprint with tests and CI checks. I’m comfortable with Discord sync and weekly camera calls, no issue at all. Let’s schedule the interview and move ahead. Warm Regards, Farhin B.

@DeveloperStation

Hi, We’ve developed several mobile apps that let users manage their cards, including one that integrates with multiple banks to fetch transaction data and display it in a user-friendly format. We also built a secure admin panel for super admins to manage users and cards, ensuring that only verified users can access sensitive data. In addition to Flutter, we’re proficient in backend technologies like Node.js and PHP, which means we can handle both front-end and back-end tasks seamlessly. We also prioritize CI/CD pipelines to ensure that only production-ready code is deployed. Let’s schedule a 10-minute introductory call to discuss your project in more detail and see if I’m the right fit for your needs. I’m eager to learn more about your exciting project. Best regards, Adil

@AnhTVc

Hi, I’d love to help you push this Flutter codebase to a truly clean, domain-driven standard while continuing to ship real card-management features. I’m comfortable working in Flutter with Clean Architecture (presentation/domain/data layers), enforcing clear aggregates, entities, use-cases, and repository boundaries so the app stays testable and scalable as it grows. I have hands-on experience integrating secure REST and GraphQL APIs, handling token refresh flows, encrypted local persistence, and structuring state management with Riverpod and Bloc depending on domain complexity. Refactoring legacy modules to remove tight coupling, eliminate analyzer warnings, and improve test coverage is something I genuinely enjoy—not just feature building. I work comfortably with async collaboration and can overlap with Japan business hours for stand-ups and sprint reviews, and I’m fully fine with weekly camera-on calls to stay aligned. You’ll get clean pull requests, documented domain models/use-cases, and at least one fully tested end-to-end feature per sprint. Happy to jump on a call, review the current architecture, and outline a refactor + feature roadmap together.

@mahig47

The goal is to strengthen the app’s foundation using Clean Architecture and Domain Driven Design while ensuring secure, scalable, and maintainable feature growth across both iOS and Android. My focus will be on refactoring existing modules into a properly layered architecture, implementing new card management capabilities, and integrating secure REST or GraphQL services, local storage, and robust state management using Riverpod or Bloc. The application will ensure high performance, strong security practices, and long term maintainability. I specialize in Flutter cross platform development with Clean Architecture, scalable state management, and secure fintech integrations. My focus will be on delivering well structured, testable, and production ready code that supports smooth card operations and future feature expansion. Let’s connect to review your current Flutter codebase and plan the next phase of scalable and secure development. Best regards, Nikita Gupta.

@shakeebsun

Hello, I’m a senior Flutter developer with strong experience applying Clean Architecture and DDD in production apps, using Riverpod/Bloc with test-driven workflows. I’ve refactored large Flutter codebases into layered, domain-focused structures with clear use-cases, repositories, and zero analyzer warnings. I’m comfortable integrating secure REST/GraphQL APIs, local persistence (Hive/Drift), CI pipelines, and writing solid unit & widget tests per sprint. Timezone alignment with Japan (UTC+9) works for me, and I’m fine with weekly camera sprint calls and structured PR reviews. I’m ready to take ownership of the codebase, stabilize the architecture, and consistently ship high-quality card management features.
