Project Challenge:

Simdisa was developed in response to our client’s concerns regarding the high operational costs of managing third-party marketplaces. To address this challenge, we built a dedicated platform aimed at reducing financial burden and improving efficiency, successfully lowering operational expenses by more than 15%. A key objective was ensuring users could enjoy an experience comparable to the conventional marketplaces they were already familiar with, so we designed a UI/UX that closely mirrors standard marketplace functionality, including shopping cart features, order management and shipping workflows, as well as integrated payment systems. On the administrative side, we implemented a comprehensive dashboard featuring incoming order management, order history tracking, and bookkeeping processes, providing full visibility and operational control.

Steps:

Login as admin or customer.
Customer: choose product, add to cart, choose shipment, checkout payment.
Admin: add product and stock, automation order process, process items for delivery.

Tech / Framework:

Next.js + TypeScript
Tailwind CSS + shadcn/ui

Achievement:

I do the full-stack development of Simdisa, from planning the business logic to deploying the production environment. I designed and implemented the automatic order system decrease human error up to 80%, make distributor price feature, and also integrated shipment. I integrated the Xendit payment gateway and built a smooth checkout process while ensuring transaction reliability and data consistency. I also focused heavily on responsive design, scalability, and database optimization for multi-seller environments.
