Food Delivery
This project is a comprehensive next-generation food delivery ecosystem. It consists of three independent applications, interconnected through a shared real-time PostgreSQL database, and designed to cover the entire value chain: from the customer to the driver, through the restaurant operator. The 3 Applications 📱 Client Application (React Native - Mobile) The consumer-facing application. It covers the entire purchase journey, from meal discovery to real-time delivery tracking. 🚗 Driver Application "Le Coursier" (React Native - Mobile) The field logistics application dedicated to drivers. It manages ride acceptance, background GPS tracking, and delivery confirmations. 🖥️ Admin Hub "Le Pilotage" (React Native Web - Tablet/Desktop) The control center for operators and restaurant owners. It provides 7 management modules covering restaurants, menus, orders, drivers, pricing, concierge service, and dispute resolution. This Food Delivery ecosystem is not an MVP (Minimum Viable Product). It is a complete, asynchronous, reactive, and secure software foundation covering the entire food delivery value chain. The architecture of three micro-applications connected via PostgreSQL Realtime guarantees: - Horizontal Scalability: Each application can evolve independently. - Transactional Integrity: PostgreSQL ACID compliance for orders and payments. - Real-Time Experience : Near-zero latency between the driver in the field and the client on their phone. - Business Intelligence: Nutritional matching, dynamic pricing, and gamification natively integrated.

CUBER AI-Powered Business Simulation and Prototyping Platforms
Cuber is an enterprise-grade, AI-orchestrated business operating system that consolidates the entire venture lifecycle from market intelligence and strategic planning to operational execution and investor readiness into a single, composable platform. The platform serves 19 independent modules organized across three verticals: - Startup Toolkit(9) | AI-driven strategic engines | Sentiment Analytics, JTBD Ideation, Strategy Engine, Pitch Deck Generator, Executive Summary | - Business Operations (4) | Operational management | Execution Hub (Kanban), Social Inbox, CRM, Resource Manager - Tools (6) | Standalone utilities | Email Pro (SMTP), Landing Page Generator, Legal Hub, Videoconferencing What makes Cuber architecturally unique: every module functions as an autonomous, atomic unit yet any combination of modules can be composed at runtime to produce aggregated, high-value outputs. A user can launch the Strategy Engine in isolation, then weeks later merge its data into a Pitch Deck that also pulls from Sentiment Analytics and Founder-Market Fit all without a single line of glue code.

Gvalo Automated SaaS Accounting Platform
GVALO is a fullstack SaaS platform (Web + Android Mobile) that automates the entire document and fiscal lifecycle of an accounting firm. It covers the complete chain: document collection*(from the client's cloud or mobile app) → intelligent extraction (OCR + LLM) → accounting qualification** → structured archiving in the client's Drive → tax declaration generation**. The ambition is not to be a "scanning tool" but a true accounting co-pilot, capable of making autonomous decisions across the entire document pipeline. Architectural Synthesis GVALO distinguishes itself through Enterprise-grade software design. By combining the robustness of TypeScript/Next.js, the absolute isolation of PostgreSQL RLS, and defensive AI algorithms (fallbacks, retries, schema validation), the engineering team has built a system capable of absorbing massive scale while guaranteeing bit-perfect accounting integrity. This highly modular architecture empowers the platform to innovate rapidly while maintaining the uncompromising reliability required by financial institutions.
