Crypto E-commerce System: Auto-delivery, Sub-domain Routing & USDT Checkout

Project Title: SaaS E-commerce Platform (PHP/Vue) with TRC20 USDT Payment & Multi-tenant Automation About the Project: We are looking for an Expert Full-Stack Software Engineer or a Professional Development Team to design, architect, and build a highly secure, automated digital goods (Faka) e-commerce platform with advanced multi-tenant SaaS capabilities from scratch. The system will operate globally, supporting 18+ languages, and must feature a robust infrastructure capable of handling high-concurrency API integrations and decentralized crypto assets. Core Architecture & Tech Stack Preferred: Backend: PHP 8.x (Laravel or Webman framework preferred for application management). Frontend: Vue 3 + Pinia + Vue-i18n (Responsive, Mobile-First UI/UX tailored to modern e-commerce flows). Database & Cache: MySQL 8.0 + Redis (Distributed locks, high-frequency queuing). Infrastructure: Nginx (Wildcard server blocks for dynamic subdomain routing). Key Modules Included: SaaS Multi-tenancy: One-click automated sub-site deployment, complete database isolation per tenant (Tenant_ID), and independent financial ledgers. Universal Supply API Adapter: A visual backend interface allowing us to map external supplier APIs dynamically using JSON Path rules. Anonymous USDT (TRC20) Payment Network: Integration with non-KYC third-party gateways alongside a native TRON blockchain block listener for temporary unique address allocation and automated multi-sig wallet aggregation. Smart Domain Rotation Pool: Automated global connectivity polling (every 10-30 mins) with seamless, zero-downtime rotation for blocked domains. Telegram Customer Support Module: Dedicated configurations to dynamically bind, manage, and render Telegram handles across main and sub-sites. Advanced Risk Control: Intelligent IP firewalls against scrapers/DDoS and a strict automated midnight dual-core financial reconciliation cron job. Detailed Requirements Attached: We take project specification very seriously. Therefore, we have attached a meticulously detailed 36-Core Feature Requirements Matrix (Excel file). Apart from standard guest checkout flows and member centers, all advanced logics—including the mathematical constraints for financial auditing and Nginx routing—are clearly defined in this spreadsheet. Please download and carefully review the attached Excel file before submitting your proposal. Important Communication Notice: Please note that the Project Manager (PM) for this project is not a native English speaker. All daily communication, milestone evaluations, and code revision requests will be conducted via high-quality translation software (e.g., DeepL / Google Translate). We expect developers who are highly patient, structured, and capable of working with clear written technical documentation. How to Apply: To filter out automated bot proposals, please start your response with the phrase "OmniNexus Architect". Proposals without this phrase will be rejected immediately. In your bid, please state your estimated timeline and experience regarding SaaS architecture and TRON network integrations.
