Descripción de la oferta

This project starts from a blank slate: I need a full-stack, production-ready business management web application that unifies ERP, CRM, inventory, billing and accounting features in a single responsive interface. Scope of work • Front-end: React.js with modern component architecture, state management and a clean, mobile-first UI. • Back-end: Node.js + Express.js powering a REST API that the front-end will consume. • Data: PostgreSQL for core transactional records and MongoDB for any unstructured modules; well-designed schemas and migrations are essential. • Core modules: customer relationship tracking, product & stock control, purchase/sales orders, invoicing, multi-stage accounting, plus an admin dashboard with real-time KPIs. • Security: JWT-based authentication with granular role management. • Integrations: payment gateways, email services and WhatsApp messaging through third-party APIs. • DevOps: containerised deployment to Vercel, Render or another cloud platform with CI/CD pipelines, monitoring and graceful roll-back strategies. Primary goal The assignment is to build an entirely new application, not merely polish an existing codebase. Proposal expectations Please attach a detailed project proposal describing your system architecture, technology choices, milestone breakdown, estimated timeline and any similar work you have shipped in React / Node ecosystems. Highlight performance optimisation strategies and how you plan to keep the codebase maintainable. Acceptance criteria 1. Fully functional web app covering the modules above. 2. Responsive UX verified across major browsers and devices. 3. API documentation (OpenAPI / Swagger). 4. Automated test coverage for critical paths. 5. One-click cloud deployment with staging and production environments. With these points covered I will be able to move quickly from review to kick-off and keep the build on schedule through clear, iterative milestones.
