Welcome to supplymars
Your One-Stop Shop for Life on the Red Planet
Pioneering Commerce Beyond Earth
Whether you're managing a Martian colony or stocking up for your next extravehicular adventure, Supplymars is your destination for everything from habitat maintenance to cutting-edge scientific equipment.
It's also a fully functional demo designed to showcase e-commerce development with a modern PHP stack — modelling real operational complexity, not just add-to-cart basics.
The Platform
Built for Modern E-commerce
Product Management
Full product catalogue with categories, subcategories, images, and manufacturer associations.
Supplier Management
Multiple suppliers per product with cost tracking, stock levels, and supplier product catalogues.
Order Processing
Customer orders with line items, status tracking, and automatic allocation to supplier purchase orders.
Purchasing
Purchase orders generated from customer demand, tracked through acceptance, shipping, and delivery.
Pricing & VAT
Configurable markup strategies at multiple levels, VAT rate management, and sell-price calculation.
Reporting
Dashboards with revenue, margin, and order metrics. Daily granular records aggregated into fast summaries.
What's Under the Hood
Real Operational Complexity
Multi-supplier Sourcing
Products aggregate multiple supplier sources. A best-source algorithm picks the lowest cost, with automatic cost optimisation and stock-aware allocation across every product.
Dynamic Pricing Cascades
Three-level markup cascades across product, subcategory, and category with pretty-price models and event-driven recalculation.
Order Line Splitting
When no single supplier can fulfil the required quantity, order lines can split across multiple suppliers. Overall status is derived from the lifecycle of the resulting purchase order items.
Purchase Order Lifecycle
Full lifecycle management from allocation through acceptance, shipping, and delivery with state-machine transitions and domain event propagation.
Simulation-driven Design
Console commands drive the full order, purchasing, and fulfilment lifecycle with realistic timing, automated stock fluctuation, and two-layer reporting aggregation.
Built With
Modern Stack, Proven Patterns
DDD Architecture
Modular monolith with bounded contexts, CQRS command/query separation, and domain events driving cross-context communication.
PHP 8.5 + Symfony 8
Modern PHP with readonly classes, enums, and constructor promotion. Symfony powers the web UI, console commands, and a REST API with OpenAPI docs.
Hotwire + Tailwind
Turbo Frames and Streams deliver SPA-like navigation without page reloads. Stimulus adds targeted interactivity. Tailwind handles responsive styling.
Infrastructure
MySQL 8.4 with Doctrine ORM, RabbitMQ for async event processing, Redis for caching and sessions, and S3 for file storage. Deployed on AWS EC2.
