Property Management Web & Mobile Platform

What I need
I am a private UK landlord with residential properties. I need a personal property management Progressive Web App (PWA) built for my own use this is NOT a SaaS product or a startup. It is a private tool for my portfolio only.
I have an existing reference product I’sd like to follow. Build me something similar in look, feel, and function, with additional features listed below.
I also have a fully working React prototype already built. This covers the UI, user flows, and logic. You are not designing from scratch — you are engineering a production-ready app from existing work.

Tech stack
Component Technology
Frontend React 18
Database Supabase (PostgreSQL + Storage)
Auth Supabase Auth
Hosting Vercel
Email notifications SendGrid
Push notifications PWA Service Worker
PDF generation React-PDF or jsPDF

Additional features
1. Court-ready fault transcript
Every fault reported through the tenant portal generates a full timestamped communication transcript. Every action — reported, acknowledged, contractor booked, resolved — logged with exact date and time and who performed it.
One button generates a print-ready PDF formatted for court submission including:
• Property and tenant details
• Full chronological transcript
• Statement: "All entries timestamped at point of submission. Cannot be retrospectively altered. Suitable for county court submission."
2. Two-sided tenancy journey
Visual step-by-step journey both landlord and tenant can see:
• Property Setup
• Tenant Onboarding
• Tenancy Agreement
• Deposit
• Move In Inventory

When landlord books a contractor — tenant sees contractor name, date, and time in their portal automatically. No more tenants asking "when is the repair person coming."
