mobile app + customer communication design

when Dechoes Resale lost access to Instagram, their primary communication channel, i led the design of a mobile app to restore and improve how the brand connects with customers. working within Shopify and Tapcart constraints, i created a mobile-first experience that enables real-time communication through push notifications while improving product discovery and engagement.

problem

Dechoes Resale lost access to their primary communication channel, disrupting visibility for new arrivals and impacting customer engagement.

goals

- restore direct communication with customers
- increase visibility of new inventory and promotions
- create a scalable system for ongoing engagement

research

i conducted user interviews and surveys to understand customer needs:
- users wanted immediate access to new inventory
- users valued being first to know about drops
- users preferred direct communication over social platforms

solution exploration

i explored multiple approaches including email, SMS, and mobile solutions. based on user needs and business constraints, a mobile app emerged as the most effective solution.

implimentation

i led the end-to-end implementation of the mobile app using Tapcart, transforming the existing Shopify store into a functional mobile experience.this allowed the business to quickly launch a scalable solution without building from scratch.

user persona

meet jada: a 30-something nail technician and single mother to one young child. she prefers to shop for trendy second-hand items locally within her community, but doesn't have the time for thrifting anymore. she has been shopping at Dechoes Resale since high school and loves finding unique items at great prices.

gains

- saving time by shopping curated second hand stores instead of digging through thrift stores
- in-person shopping within her community

pains

- losing out on that special item because someone else beat her to it
- finding an item she loves that is not in her size or is out of her budget

information architecture

i structured the app to prioritize fast access to new arrivals while supporting key informational needs. my goal with this app was to maximize what our users wanted from this app: direct and quick access to new arrivals. the app also needed to host a number of pages that would share information with our users about authentication processes, shipping times, selling their items, etc. below represents the site map that optimized the layout of where all this information would go within the limitations of the Tapcart system.

design elements

i evolved Dechoes Resale’s visual identity for mobile, emphasizing a trendy, edgy, and urban aesthetic aligned with the target user. design decisions focused on clarity, strong hierarchy, and fast browsing behavior.
