About the products

Chip is an e-commerce platform specializing in print-on-demand products that offer packing, shipping, and customer services for entrepreneurs. Merchants can create a store where they can market and sell customized products with their designs.

TeeChip is the marketplace for Chip sell-side to list their products. This is where we serve our buy-side consumers.


Scalable was losing sellers to competitors for not providing product customization on Chip, an eCommerce platform.

Product customization is a rapidly rising trend in the print-on-demand market. Consumers value items that can convey individuality for the person who bought or received them as a gift. Our merchants requested the ability to create personalizable products. We were seeing a pattern of sellers leaving our platform because we didn't offer customization.

 2. Buyers: the ability to purchase products customized for themselves or as gifts for their loved ones


Personalized text project involved three different platforms: seller-side platform, buyer-side marketplace, and customer service platform. To make this case study more concise, we will focus on the seller-side platform and buyer-side marketplace.

project scope


process: kick-off iterations usability testing implementation launch


Customizable text for print-on-demand products was the most requested feature at this time, based on customer feedback. The data team also conducted market research to validate the revenue potential. Afterward, I started this project by conducting a competitive analysis to help the team prioritize which functionality we should offer in each phase.

☝🏻 I compared our competitors features for text personalization and used that to prioritize our product offers



I worked on the seller side first, as it is the most complex part. We needed to consider fulfillment aspects, as we have a mix of in-house and 3rd parties to produce customization products seamlessly. We ensured product mockups on the back end match designs that the merchant created, to show buyers a preview that matches the final product that they will get as close as possible. I listed the user flow total of 26 use cases to predict potential edge cases that systems need to prevent.

sell-side iterations

☝🏻 I explored customized tool placement and decided to redesign the page layout


I researched our competitors, looking for inspiration, and then created a rough wireframe to discuss feasibility with the development team early on. Project managers wanted a way to disable features if they hurt conversion, so we built the experience in a modal. 70% of order purchases happen on mobile, so we targeted the mobile experience first, then desktop.

Usability testing

I planned usability testing, prepared clickable mocks, and then gave the materials to the seller support team to conduct testing in Vietnamese. We conducted usability testing with five high-performance sellers who also use personalization tools on other platforms.

I worked closely with the engineering team to clarify any team concerns between our system and the design. I then worked on visual quality assurance to make sure the products were working well before launch.
