Domiva

Domiva is property-management software for Rwanda. Managers and owners run units, leases, invoices, payments and maintenance in one place, and tenants pay rent and raise issues from a mobile app. I co-founded it, ran it as CEO, and built nearly all of the product myself: the web app, the API, the tenant app and the background jobs.

The problem

Many property managers track rent and tenants in spreadsheets and chat threads. Rent is chased by hand, owners can't see how their properties are performing, and tenants get no reminder before a payment is due.

What it does

• For managers, owners and staff: units, leases, recurring invoices, payments and receipts, expenses, maintenance and tasks, a booking calendar, public listings with reservations, and owner dashboards.
• For tenants: a mobile app with push notifications in several languages, to pay rent and report issues.
• Payments by mobile money, with receipts, plus PDF and Excel exports.
• Reminders that run themselves. Scheduled SMS and push reminders, recurring invoices, and live updates across the app.
• An AI assistant that answers owners' questions about their portfolio.
• Teams and plans: roles and permissions, and subscription tiers with an upgrade flow.

How it's put together

Domiva is a TypeScript monorepo. The web app (Next.js) and the tenant app (React Native) share one typed API, so changing an endpoint is checked in both clients at compile time. Background jobs handle reminders and recurring invoices, and every job is guaranteed to run exactly once.
