Reserva INK is a Brazilian platform that enables users to create their own branded apparel without holding stock. The business model allows sellers to sign up, customize products (e.g.

About the project
T-shirts, apparel) and have them produced and shipped by the platform when orders come through. The site also offers a “university / course” section for members, helping them build their brand and scale. Features include user dashboards, product customization, order handling, and integration of marketing and analytics tools.
What had to be solved
- Implementing a smooth product customization & configurator interface (size, colors, design) that works in real time.
- Integrating the front end with MySQL backend logic to handle dynamic product data, inventory, pricing, order triggers, etc.
- Ensuring performance & responsiveness given the heavy use of images, product previews, and custom scripts.
- Making sure the site remains fluid and intuitive on mobile & tablet devices.
- Handling integrations (payment, order management, printing backend) without breaking user flow or increasing page load times.
How it was built
- Built custom Elementor templates and modules for product display, customization panels, pricing previews, and user dashboards.
- Developed back-end logic in PHP / MySQL to tie the product configurator to order generation and print backend workflows.
- Used jQuery & core-js for live updates in customization (color changes, preview updates, cost recalculation) with asynchronous requests to server where needed.
- Optimized images, used lazy loading, deferred noncritical JS, and compressed assets so the site loads quickly and smoothly.
- Tested fully responsive layouts and interactions across various devices to maintain usability of the customization tools.
What it delivered
- Delivered a robust print-on-demand platform where brands can launch products without inventory.
- Users can easily customize and preview apparel designs, place orders, and track them, all within a seamless UI.
- Back-end integration ensures orders move automatically from site to production without manual steps.
- Performance and responsiveness improvements make the site usable even on mobile devices.
- The design, development, and feature set help Reserva INK compete strongly in the custom apparel / POD industry.
