Demo project - fictional, seeded US data
Rentovyn: Rental and Property Management Platform (Demo Project)
Rentovyn is a demo rental and property management platform we built to show how one system can serve everyone in a rental business: property managers, owners, tenants and vendors, each with their own portal, plus AI that triages maintenance and flags risk early. It runs on fictional, seeded US data.
Overview
Rentovyn is one platform with four portals. Property managers run the portfolio, owners see their properties and statements, tenants pay rent and log maintenance requests, and vendors receive and close work orders. A public marketing site shows available units from the live database, with Apply links that feed straight into the online application workflow.
The problem and the goal
Small and mid-size property managers often juggle rent, leases, maintenance requests, vendor jobs and owner reports across spreadsheets, email and phone calls. Late rent goes unchased, tickets sit untriaged, and owners wait for their statements.
Demo goal: one platform for managers, owners, tenants and vendors, with AI that triages maintenance and flags risk early.
Problem framing is the demo's design brief, not a client's story.
Who it's for
- Residential property management companies with 40-1,000 units
- Owner-operators and family landlords with multi-property portfolios
- Build-to-rent and student-housing operators who want a branded resident portal

Build approach
- A TypeScript Node.js/Express API with Prisma, so the data model is typed from the database to the endpoint.
- A React/Vite front end with role-based portals, so each user type gets a focused experience on shared data.
- AI behind a provider-agnostic layer with a mock mode, so the AI provider can change without touching the app.
- Seeded data, automated tests and smoke checks, so every screen can be explored and every release is checked.
Screenshots
Any portfolio stats, occupancy or currency values visible in screenshots are fictional seed data.
