Offer Flow Complexity and Frequent Changes

The Offer Flow required constant updates as pricing logic, UI elements, and A/B tests changed over time. The team had to keep the flow clear and responsive. New designs and business rules often appeared close to release dates.

Solution

We built a custom price selector and adjusted the Offer Flow architecture to support flexible updates. This approach allowed fast UI changes and stable behavior. The core purchase logic remained intact under frequent revisions.

High Resource Usage in Video-Rich Feeds

Video content placed a heavy load on mobile devices. The feed had to display multiple videos simultaneously without freezes, delays, or excessive battery usage. This requirement made performance and stability a constant concern.

Solution

We created and implemented the custom logic for videos so they load with no delays and efficiently use the resources of a device. As a result, users can check the product items in dynamic videos and enjoy the app working with no delays.

Black Friday Campaigns with Fixed Deadlines

Black Friday represents the most demanding period for the GOAT mobile apps every year. Campaign concepts, designs, and requirements change frequently during the final weeks before launch. The apps must support complex campaign mechanics such as raffles, product drops, mini-games, and special navigation elements under strict deadlines.

Solution

We prepare the apps for Black Friday with flexible feature structures and early technical setup. This allows the team to apply late design and content changes without risk to core functionality. We also focus on performance and stability to keep the apps reliable during peak usage.
As a result, each Black Friday campaign launches on time and supports a large share of active users without stability issues.

Buyer and Seller Logic Consistency

GOAT combines buyer and seller experiences across separate platforms with shared business logic. A user can purchase items, track orders through verification and delivery stages, and later resell owned products through a connected seller flow. These scenarios require precise state handling and consistency across apps.

Solution

We implemented clear state management and well-defined flows for purchase, ownership, resale, and order tracking. This approach keeps buyer actions predictable and aligned with seller-side processes, even as items move through verification and warehouse handling.

Size Conversion Across Global Standards

The app supports size conversion across multiple systems, including US, EU, UK, and JP. Edge cases, such as children’s and gender-specific sizes, increase the risk of incorrect mappings. Any error directly affects purchase decisions and user trust.

Solution

We worked with defined conversion rules and validation logic to handle size mappings correctly across regions and categories. The solution prevents incorrect matches and presents accurate size information throughout the buying flow.
