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. 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.
Challenges
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.
Solutions
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.
Results / Conclusion
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.
