NSpare

NSpare is an auto-services platform for the market that connects vehicle owners with verified mechanics, towing providers, spare-part vendors, and logistics partners. It covers the full vehicle ownership journey: finding trusted technicians nearby, booking repairs or roadside support, ordering genuine spare parts, paying through an in-app wallet, and communicating with providers through chat, voice, and video calls. The product ships as a production mobile app on Android and iOS with a companion web presence.

Built customer-facing and provider-side feature modules in Flutter, integrated payments, messaging, and calling, and supported release workflows through automated CI/CD pipelines.

• Location-based discovery of verified mechanics, towing services, and spare-part vendors.
• Booking flows covering service requests with address, vehicle details, schedule, and issue description.
• A spare-parts marketplace with cart, orders, saved items, ratings, and reviews.
• An in-app wallet with Paystack card funding, bank account resolution, withdrawals, transaction history, and wallet PIN security.
• Provider dashboards for mechanics, towing companies, spare-part vendors, and logistics partners, including booking insights and service charge management.
• Real-time chat plus in-app audio and video calls between customers and providers.
• Saved vehicle profiles, notifications, promotional listings, and a support center.

The app was structured as a modular Flutter codebase organized around product areas, with each feature owning its own bindings, controllers, views, and data layer. Release work was automated end-to-end so builds could move from development to store distribution without manual steps.
