I need a senior-level Flutter engineer (5 + years hands-on) to take charge of a peer-to-peer mobile application that must run seamlessly on both iOS and Android from a single codebase. The core job is to own feature development end-to-end: architecting clean Dart code, wiring up real-time data flow, refining UI components for multiple screen sizes, then shipping fully tested builds to the App Store and Google Play. The project already has a high-level product roadmap; you will turn that vision into production-ready widgets, state management (Bloc or Provider is fine), secure API integrations, and smooth animations. Regular collaboration with our designer and back-end team happens in Slack and Jira, with code reviews in Git. I release milestones every two weeks, and each sprint should close with: • A compiled iOS and Android build (TestFlight / internal track) • Source in our Git repo with clear commit history • Brief release notes and any migration steps Strong knowledge of Firebase, REST or GraphQL, and automated unit / widget testing will help you move quickly. If you have published P2P or finance-oriented apps before, please highlight them and note your role. Drop a short note outlining your relevant Flutter experience, a link to at least one live app, and your earliest start date—then we can dive straight into the repo.

Hello! I’d be excited to take full ownership of your cross-platform P2P mobile app and drive it from feature specs to store-ready releases every sprint. I’m very comfortable working in product-driven environments where clean architecture, reliable real-time data, and predictable delivery cycles matter more than quick hacks. Here’s how I’d approach your project: • Architect a scalable Flutter codebase using Bloc or Provider (based on current repo patterns) • Build production-grade widgets optimized for multiple screen sizes and device classes • Implement secure real-time data flows using Firebase / WebSockets / GraphQL subscriptions • Integrate APIs with proper token handling, refresh logic, and error boundaries • Maintain smooth 60fps animations and platform-consistent UX across iOS and Android • Set up strong automated testing (unit + widget + critical integration paths) Sprint delivery discipline: • TestFlight + Play Internal build every sprint • Clean Git commits + PR-ready structure • Clear release notes + migration steps What you’ll get from me: • Senior-level Dart architecture with strong separation (data / domain / presentation) • Production-safe state management and offline-safe patterns where needed • Performance profiling and memory optimization • Store submission support and build pipeline stability • Clear async communication via Slack, Jira, and Git reviews Happy to review your repo and propose first-sprint priorities. Best regards, Jasmin

I’ve worked on several Flutter apps with real-time features and clean architecture that ran smoothly on both iOS and Android from a single codebase. For example, I helped build a finance app with secure API integration and state management using Bloc that required seamless syncing and polished UI for different screen sizes. To move fast, I’d start by reviewing your existing roadmap and repo to align on architecture and best practices for state management and API security. Do you currently use GraphQL or REST for your data layer? Also, how are you handling real-time updates—Firebase streams or another method? I’m comfortable shipping TestFlight and Play Store builds with clear release notes and migration steps every sprint, ensuring your milestones close cleanly. I’m ready to jump into the repo and sync with your designer and backend team on Slack and Jira right away. What’s the earliest you need the first sprint delivered? I can start as soon as tomorrow.
