TradePost

The Product

TradePost is a two-sided home-services marketplace built for South Africa. The loop is simple: homeowners post a job, compare quotes from verified pros, and pay by milestone. Providers get verified, win leads, get paid. The pillars are KYC, milestone payments, in-app chat, and map discovery. In-app copy reflects the market. Jobs are priced in Rand. Categories cover plumbing repair and geyser replacement.

The Foundation

The mobile app codebase is internally known as quote-it or kmm-boiler. It uses Kotlin Multiplatform with a shared Compose Multiplatform UI for Android and iOS. The stack is specific: Kotlin 2.2.20. Compose Multiplatform 1.9.3. Ktor 3.3.1 for networking. SQLDelight 2.0.2 for the local database. Koin 4.1.0 for dependency injection. Decompose 3.5.0 handles navigation. Coil 3 does image loading. SKIE handles Swift interop for iOS. Backend and auth run on the Supabase Kotlin SDK 3.2.5. Maps use MapLibre Compose. Checkout happens in a Paystack-based in-app WebView.

Architecture follows a strict MVI pattern. ViewModels extend MviViewModel<State, Intent, Effect>. The codebase uses clean architecture layers: data, domain, and presentation. Platform-specific code uses expect/actual declarations. Build config relies on convention plugins.

Where It Stands

This is a build log, not a launch post. TradePost is in its foundation phase and the codebase moves every week — there's an active changelog to prove it. Current work is hardening the UI, accessibility, and the core design system: a real component library of buttons, cards, lead cards, milestone timelines, and hero image cards, every one covered by automated Roborazzi screenshot tests. What isn't here yet is an app-store listing and user numbers — that's the next chapter, not a caveat.
