CHALLENGE & SOLUTION
Buying materials takes more than a simple cart.
Dimensions, quantity, payment terms and delivery shape a purchase. Product supply, preparation and seller settlement also need operational control.
Supplier journey
Manage products, prices and variants, own orders, sales reports and outstanding settlement amounts.
Administrator journey
Oversee customers and sellers, control orders and payments, seller shares and marketplace content.
One order can involve multiple suppliers.
Customers place an order through one journey, while items can belong to different sellers. Each seller's order status and financial share are tracked separately. Administrators have an overall view, while sellers see their own information.
The challenge
Buying stone and building materials involves more than a photo and a quantity. Buyers need to consider materials, dimensions, area, payment terms and delivery, while suppliers manage prices, stock, orders and their financial shares. The challenge was to connect these decisions and operations in a specialized marketplace with a clear buying experience and centrally managed workflows.

My contribution
Lead Developer & Project Manager
As lead developer and project manager, I connected the customer experience, supplier panel and central administration. My work covered full-stack development, catalog and order logic, payments and installments, sales and settlement reporting, and linking image simulation to the catalog. Project management focused on coordinating these journeys and translating the materials market's specialized needs into a usable product.
Key system design decisions
Shared core, specialized experience
Dizaka builds on a shared commerce core with views and logic tailored to materials, dimensions and images.
Seller-specific data scope
Order, sales and settlement reports are scoped by seller identity. Administrators retain an overall marketplace view.
Payments separate from seller shares
Customer payments, order status and seller shares are tracked separately so receiving a payment is distinct from settling a seller's balance.
Image processing linked to products
Material images can come from the catalog. Requests, processing status and outputs remain linked to customer accounts.
PRODUCT CAPABILITIES
Specialized selection. Managed operations.
Dizaka connects material selection to real sales operations, from dimensions and images to payment, supplier orders and settlement.
