Flutter Developer Needed for Tradingapp – Clean Architecture Foundation (Branding + Auth Ready) We are building ProffTrading, a modern financial trading application. This project focuses on delivering a clean, scalable, high-quality Flutter foundation that we will build advanced features on later. This is NOT a UI-design job. You will build the architecture, navigation, auth structure, tier logic, and integrate branding assets. --- Modern Device Support (Required) The app must be structured for: Latest Android API levels Modern iOS devices (iPhone 12 → 15+) Smooth navigation and transitions Performance-oriented code We are targeting modern mobile hardware, not legacy devices. --- Intellectual Property All work is 100% private IP. You may NOT: Upload code to GitHub or public repos Share the project externally Reuse the project in any other work All files must stay inside Freelancer or my private git repository. --- Branding, Logos & Icon Packs I will provide a full branding package (after project start), including multiple versions of: App logos Launcher icons (Android/iOS) Splash screens Tier/VIP icons Navigation icons You are not locked to a single version — use what fits best. Expected asset folder structure: assets/ logos/ icons/ splash/ tiers/ navigation/ Your job: integrate assets cleanly (no design work required). --- Authentication + Tier System You will deliver: Login screen Register screen Mock authentication logic Basic user model: name, email, tier Tiers: Copper Silver Gold Platinum Diamond Routing: Tier Dashboard Copper–Platinum DashboardBasic Diamond DashboardDiamond Prepare architecture for Supabase or Firebase integration later. --- Navigation & Main Structure Use: Clean Architecture Feature-first structure Riverpod (preferred) GoRouter Main tabs: Home Search Markets Portfolio Settings Screens may be simple placeholders — focus on structure. --- REQUIRED PROJECT STRUCTURE (CLEAN ARCHITECTURE) (Dette er nøkkelen til at appen er profesjonell og skalerbar) lib/ app/ # App entry, router, global setup core/ # Theme, constants, shared utilities, tier definitions services/ # Backend-ready services (Supabase/Firebase placeholders) features/ auth/ domain/ data/ application/ presentation/ dashboard_basic/ domain/ data/ application/ presentation/ dashboard_diamond/ domain/ data/ application/ presentation/ search/ domain/ data/ application/ presentation/ instrument_detail/ domain/ data/ application/ presentation/ portfolio/ domain/ data/ application/ presentation/ settings/ domain/ data/ application/ presentation/ Architecture Rules: No business logic in UI No direct access to backend inside widgets All external data flows through repository interfaces Replaceable mock → real implementation without changing UI State managed with Riverpod providers Router logic stays in app/[login to view URL] This ensures long-term scalability and clean engineering. --- Dashboards Two modules only: DashboardBasic DashboardDiamond Both should be modular placeholders, ready for future complex UI. --- Search & Instrument Detail Templates Search: Search bar Mock result list Instrument detail template: Chart placeholder Instrument info area Signals section News placeholder Buy/Sell placeholders No real functionality yet. --- Portfolio Template Using mock data: Balance Positions Unrealized PnL Transaction list Simple, clean, and extendable. --- Backend Structure Preparation You must prepare clean architecture for future integration with: Supabase (preferred) or Firebase Create repository interfaces: AuthRepository MarketDataRepository PortfolioRepository Use mock implementations now. Architecture must also support: Real-time updates Payment systems (Apple/Google/Stripe) AI modules later Advanced market feeds --- Quality Expectations We want: Clean, maintainable architecture Clear naming Modular and scalable code Smooth navigation Professional best practices A developer who can suggest improvements --- Documentation Requirements Final milestone must include: Folder structure explanation Architecture overview Tier routing logic Navigation diagram How to integrate real APIs later Where payments will plug in iOS + Android setup instructions Where AI, charts, and signals attach later --- Milestones (Updated – Smaller First Payment) Milestone 1 – Project setup + skeleton + asset folders (10%) (smallest milestone to verify quality) Milestone 2 – Navigation + tier routing + dashboards (25%) Milestone 3 – Search + instrument detail templates (20%) Milestone 4 – Portfolio + login/register + mock user system (25%) Milestone 5 – Documentation + final cleanup (20%) --- Goal Deliver a stable, modern, scalable Flutter foundation that enables long-term development of advanced trading features.

Hi, I went through your detailed vision for ProffTrading and I appreciate how much focus you are placing on a clean and scalable architecture. It is clear that you want a strong Flutter foundation rather than early feature heavy screens, and that approach matches perfectly with long term growth. Your structure for navigation, tier logic, modular dashboards, asset integration, and mock authentication shows a very professional direction and I am excited to help shape it into a solid and well organized codebase. Likely core features include authentication flow, tier based routing, clean architecture setup, structured feature modules, modern navigation. With more than seven years of experience building mobile and web systems, full backend setups, custom modules, and scalable app foundations, I can deliver a smooth and well aligned setup ready for the advanced trading functions you plan to add later. I enjoy creating frameworks that stay flexible and easy to extend in future phases. Let us schedule a quick chat to align your vision and next steps. Best Regards, Prasham Jain
