The Problem
Homeowners had no reliable way to find and book a local service provider they could trust - cleaning, plumbing, electrical, carpentry - without relying on word of mouth or a search engine result with no verification behind it. On the other side, the providers themselves had no real digital presence: no booking system, no reviews, no way to be found by a customer who didn't already know them.

Darwinbark built a two-sided marketplace - a mobile app and web platform - connecting homeowners with verified, rated home service professionals, with both sides of the marketplace designed as first-class users rather than the provider side being an afterthought.
Architecture
The platform runs on a shared backend serving two distinct app experiences: a customer-facing booking flow and a provider-facing job management app. Bookings move through a state machine (requested → accepted → in progress → completed → reviewed) with push notifications firing at each transition, so both sides always know exactly where a job stands without needing to check in manually.
Provider verification happens before a profile goes live - an admin approval step gates new providers from appearing in search results until their credentials and background checks clear, keeping the "verified" claim in the marketing actually true rather than a label anyone can claim.
Live location tracking during an active job uses periodic position updates from the provider's app, shown to the customer for the duration of that booking only - not persistent tracking outside of an active job.
Features
- Service category browsing (cleaning, plumbing, electrical, carpentry)
- Provider profile with ratings & reviews
- Real-time booking & scheduling
- In-app payments
- Live tracking of the assigned service provider
- Push notifications at every booking state change
- Admin panel for provider verification
Challenges Solved
Trust before the first booking. A new customer has no way to judge a provider except ratings and verification status - so the admin verification gate and a review system that only allows reviews from completed bookings (not open reviews from anyone) were treated as core trust infrastructure, not optional extras.
Two very different user experiences, one backend. Customers want simplicity - browse, book, pay. Providers want control - accept or decline jobs, manage a schedule, get paid reliably. Both apps share the same booking and payment core but present entirely different UI built around each side's actual job.
Cold-start supply problem. A marketplace is worthless without providers on it before customers arrive - the admin panel and verification flow were built to be fast enough that onboarding the first wave of providers didn't become the bottleneck to launch.
Result
The platform launched with 200+ verified providers in the first month, and customer booking completion rate reached 85% within 90 days of launch.
