Evidence
Delivered workflow scope
01 / Context
The product problem
Print ordering has to reject unsuitable artwork early, price many product and option combinations consistently, and translate an accepted order into the fulfillment provider's required format. Mistakes at any of those boundaries create manual support work or production risk.
Delivered system outcome
The delivered order flow connected artwork validation, product configuration, pricing, and fulfillment routing. Customers received earlier feedback on file suitability while accepted orders moved through a defined provider integration boundary.
02 / Product scope
What the system was built to do
Each capability is tied to the public product scope. No commercial or adoption metric is inferred.
02
Dynamic product pricing
The pricing engine resolves the selected product and print options into a consistent order price.
03
Guided order configuration
The React interface keeps artwork and product choices inside one customer-facing ordering sequence.
04
Fulfillment adaptation
The service layer maps accepted orders to the shape expected by the external SinaLite API.
03 / System flow
How the main workflow connects
- 1
A customer selects a print product and its options.
- 2
The customer uploads artwork for DPI validation.
- 3
The pricing engine calculates the configured order price.
- 4
The application accepts the completed order workflow.
- 5
A provider adapter routes the accepted order to SinaLite fulfillment.
04 / Engineering
Decisions behind the delivery
A React ordering interface collects product, option, and artwork choices. A Node.js service validates files, calculates prices, and adapts accepted orders to the SinaLite fulfillment API. The provider-specific format remains behind the service boundary.
Technology

- Node.js
- SinaLite API
- Pricing Engine
01
Validate before fulfillment
Artwork suitability is checked earlier in the journey so unsuitable files do not silently reach the provider boundary.
02
Centralize pricing rules
A defined pricing engine prevents the interface and backend from calculating the same option combinations differently.
03
Isolate the fulfillment API
A provider adapter keeps SinaLite-specific payload rules separate from the customer-facing order model.
