Building MyGreenLoop: From Idea to Reality

Frontend Layer

I chose React 18 with TypeScript for type safety and component-based development. Lightweight routing was handled with Wouter, and Radix UI provided accessible, reusable components. Styling relied on Tailwind CSS for efficiency, while TanStack Query and React Hook Form with Zod validation ensured smooth state management and form reliability. The architecture focused on reusability, responsiveness, and real-time inventory checking, with pages for home, product catalog, checkout, admin dashboard, and customer feedback collection.

Backend Layer

The backend was built with Node.js and Express.js, also in TypeScript. I implemented a RESTful API with session-based authentication for admin access, error handling, and logging. Core services included product management, rental processing, SMS notifications via Twilio, and feedback moderation. Real-time inventory calculations and admin authentication were integrated seamlessly, ensuring the platform operated reliably under multiple simultaneous operations.

Database Layer

PostgreSQL (hosted on Replit) managed all relational data. Using Drizzle ORM, I created a type-safe schema for products, rentals, rental items, inventory dates, and feedback. Inventory automatically adjusts based on rental dates, and an admin approval system controls visibility of public feedback. Proper foreign keys and relational integrity maintain consistency across all operations.

Hosting & Deployment

Both development and production are hosted entirely on Replit, providing a streamlined, integrated platform. The development environment features Node.js 20 runtime with hot reload via Vite, while production deployment is handled seamlessly through Replit Deployments with zero configuration required. The built-in PostgreSQL database integrates directly with Replit's managed service, eliminating external database dependencies.

Replit handles all infrastructure concerns including automatic SSL certificates, .replit.app domain hosting with custom domain support, traffic scaling, and resource management. The platform provides built-in monitoring with integrated logging and error tracking through the dashboard. Session management uses PostgreSQL-backed storage that's fully integrated with Replit's database service.

Key deployment features include single-click deployment from development to production, automatic HTTPS-only production environment, secure secret management through Replit's environment system, and the unique checkpoint-based rollback system that can restore both code and database state. Frontend and backend are served together on port 5000, with Vite handling frontend bundling while Express serves static assets.

The Twilio integration follows A2P 10DLC compliance for reliable SMS notifications, with environment-specific phone numbers and API credentials managed securely through Replit's system. This complete platform integration eliminates the complexity of managing separate hosting providers, databases, and deployment pipelines.

The main challenge throughout was balancing simplicity with functionality. Some initially obvious features added unnecessary complexity, so I had to constantly reevaluate decisions from a user perspective. Beyond the code, I considered the broader vision: making sustainability actionable without it feeling like a burden. That perspective guided every technical and design decision.

Finishing MyGreenLoop was rewarding because it wasn't just about writing code—it was about problem-solving, design thinking, and turning an abstract idea into something tangible. The platform is now fully functional, with real-time inventory management, SMS notifications, customer feedback collection, and a complete admin dashboard, ready for production deployment. The project reinforced the importance of iteration, user perspective, and ownership in building a product from concept to reality.
