Harbor Retail Group-KopiRabbit

KopiRabbit is a US-based online marketplace platform built to connect local communities with skilled professionals across 200+ service categories — from home repairs, legal services, and graphic design to pet care, photography, and translation.

Building a two-sided marketplace is one of the more complex web projects in the industry. The client faced several product and design challenges:

The platform had to serve two distinct user groups — clients looking to hire, and professionals looking for work — each requiring their own registration flow, dashboard, and experience. Getting this right was critical to adoption on both sides.

With 200+ service categories spanning everything from corporate law and immigration attorneys to dog grooming and tattoo removal, structuring the navigation and category architecture without overwhelming the user was a major UX challenge.

The client also needed a credibility layer built in from day one — ratings, reviews, job counts, and verified provider profiles — because trust is everything on a marketplace where strangers are hiring strangers.

On top of this, the website had to launch in sync with mobile apps on both Android and iOS, meaning every design and development decision needed to work consistently across all three platforms.

We designed and developed the complete KopiRabbit platform — website, provider-facing pages, and the CMS backbone to manage listings and categories at scale.

The homepage was built around a location-aware service search, letting users select a category and instantly browse local professionals. Provider cards were designed to surface the most trust-building information upfront: star ratings, review count, city, years in business, and jobs completed on the platform.

We created two separate onboarding flows — one for client members and one for service providers — each designed to reduce friction and get users to value as quickly as possible. Provider profile pages were given dedicated layouts with room for a business bio, service category badge, portfolio context, and review history.

The service category architecture was structured into logical groups (Home Services, Legal, Design & Web, Writing & Translation, Pet Services, etc.) with a browsable directory that works both through the homepage search and through category landing pages.

For the mobile experience, the design system was built to translate cleanly across the Android and iOS apps, keeping the visual language and core user flows consistent whether someone was on the website or on their phone.
