Web development case study
Biote Medical: Advanced Cart Price Rule Customization
Designing a sophisticated SKU-level discount engine for Adobe Commerce

Background & Challenges

- Granular Inventory Tracking: Developing a system to track "Limit Quantity" and "Used Quantity" for specific SKUs within a single rule.
- Automated Deactivation: Implementing real-time coupon deactivation at the SKU level once inventory thresholds are reached.
- User Experience: Creating a custom frontend popup to notify customers and force the removal of non-eligible items from the cart.
- Complex Integration: Ensuring seamless data transfer to fulfillment systems by adding specialized extension_attributes to the Order API responses.
AI-Powered Implementation

- Infrastructure & Schema: We used intelligent prompting to instantly generate the initial module structure and the db_schema.xml for the custom database tables.
- Data Layer Drafting: AI assisted in creating the primary CRUD components, including Model, Resource Model, and Repository classes, ensuring strict adherence to Magento's service contract patterns.
- Rapid Prototyping: The AI assistant helped sketch the initial logic for inventory-based coupon deactivation, providing a clean foundation for the final build
Expert Refinement & Validation
The AI-generated foundation was only the starting point. Our lead developers performed rigorous manual oversight to ensure the solution met enterprise-grade standards:
- Refactoring: Every line of code was reviewed for compliance with Magento Coding Standards and PSR.
- Checkout Logic: We manually implemented the intricate cart-removal logic and API attributes, which require deep expertise in the Magento checkout flow.
- Human-Led QA: While AI helped draft the technical documentation, our QA team conducted exhaustive manual and automated verification to ensure stability under load.
