Project Description We are seeking an elite Full-Stack Developer for a long-term partnership to lead the production launch and scaling of our App,. Our platform is built on the Fuodz Core (Laravel backend / Flutter apps). We are transitioning from a demo state to a high-security, city-scoped production environment in Honduras. We need a technical expert to build a robust, CEO-controlled financial engine and modernize our entire web presence. Key Technical Scope of Work 1. Dynamic Financial Engine (The Master Gateway) Agnostic Payment Architecture: Implement an Adapter Pattern for payment gateways (any). The CEO must be able to add or remove providers without core code changes. Single-Field API Support: Enable a simplified, masked input UI for gateways requiring only a "Secret Token" or "Access Key."PayPal Smart Routing: Automate the switch between Micropayments API ($< \$15.62$) and Standard API ($\ge \$15.62$) to optimize transaction fees. Wallet Management: Develop a CEO-exclusive tool to define dynamic recharge shortcuts (e.g., L 100, L 500) that update the app in real-time. 2. Governance & CEO Security Master RBAC Dashboard: Build a dynamic permission system accessible exclusively to the CEO to grant/revoke capabilities for 14 operational roles. Real-time Alerts: Implement a system observer that triggers a Push Notification/SMS to the CEO whenever any Payment Gateway or API Key is modified. City-Based Isolation: Use Laravel Global Scopes for strict data isolation across multiple cities (Tegucigalpa, SPS, Choluteca). 3. Web Modernization & UI/UX Refinement Tailwind CSS Overhaul: Full modernization of the website with a minimalist "Tech-First" aesthetic (16px rounded corners, premium typography). Critical Detail Fixing: * Repair Banner Scaling logic to prevent distortion on all mobile devices. Fix Dynamic Layout Inheritance for CMS pages (Header/Footer sync). Update all system/social icons to high-resolution SVG formats. 4. Core Stability & DevOps Fuodz Core Update: Migrate to the latest version while maintaining customizations. NDK & Mapbox Fix: Resolve Android rendering crashes by forcing ndkVersion = "27.0.12077973". Mailgun Integration: Configure full SPF, DKIM, and DMARC records for 99% email deliverability. Technical Stack Requirements Laravel 10+ & PHP 8.2+ (Expert level). Flutter & Dart (Expert level - specifically NDK and Gradle management). Tailwind CSS (Expert level for responsive modernization). Proven experience with Fuodz or similar marketplace scripts. Deep understanding of Design Patterns (Adapter, Strategy) and Global Scopes. The Ideal Candidate You prioritize Security and Financial Logic over simple UI fixes. You have a keen eye for Front-end precision (scaling and alignment). You are looking for a stable, long-term relationship (not a one-time gig). P.S.: Proposals above the specified value will be deleted. Not people from UK or USA.
