Under Active Development Private Beta Side Project PropTech & AI
Project in Active Development & Beta-Testing

GestAImmo is currently under active design and development. Multilingual resident portal modules, automated bank reconciliation pipelines (CAMT.053/OFX), and Vertex AI invoice OCR capabilities are being continuously developed and validated.

GestAImmo — AI-Native PropTech Platform

An AI-native condominium and building administration platform unifying multi-tenant resident portals, automated bank reconciliation, intelligent document OCR parsing, and multilingual operations into an intuitive cloud ecosystem.

The Challenge & Problem Space

Transforming Fragmented Property Administration

Residential building and condominium administration has traditionally been burdened by fragmented tools: desktop accounting software, disparate spreadsheets, manual paper invoices, and disorganized email threads. Co-owners face opaque expenses, while administrators spend countless hours manually matching bank entries and transcribing contractor invoices.

GestAImmo was architected from the ground up to eliminate these bottlenecks. By pairing a secure multi-tenant cloud backend with multimodal AI models, the platform turns complex property administration into an automated, transparent, and collaborative experience for administrators, co-owners, and tenants alike.

Platform Capabilities

Engineered for Efficiency, Automation & Clarity

Three Specialized Workspaces

Dedicated, role-tailored portals for Property Administrators (full financial & ledger control), Co-Owners (share breakdown, voting, balance statements), and Renters (lease documents, maintenance tickets).

Automated Bank Reconciliation

Parses CAMT.053 and OFX bank statement exports. Automatically correlates credits against co-owner quota payment requests, identifying unpaid dues and generating payment reminder batches.

Vertex AI & Gemini OCR Engine

Scans supplier receipts and invoices (PDF and images). Extracts vendor name, VAT/Tax number, invoice dates, breakdown line items, and allocates costs directly to ordinary or extraordinary building accounts.

Six-Language Native Localization

Architected for multi-jurisdiction compliance across Switzerland, Italy, France, Germany, Spain, and Portugal, accounting for localized real-estate laws, millesimal quota distributions, and fiscal calendars.

Maintenance & Supplier Workflows

End-to-end incident dispatching: co-owners report issues with photos; administrators assign pre-approved contractors; work quotes are reviewed, authorized, and logged for auditing.

Zero-Knowledge Multi-Tenancy

Granular database-level isolation. Each building, condominium syndicate, and user record is strictly protected by declarative Firestore security rules preventing cross-tenant leakage.

Systems Engineering

Cloud-Native Architecture & Data Pipeline

The architecture emphasizes zero-server maintenance, sub-second latency, and continuous automated delivery. Built with Google Cloud Serverless and Firebase:

1. Edge & Presentation
React 18 Single Page Application served via high-speed global CDN with instant route transitions, offline caching, and responsive glassmorphism UI.
React 18 Vite Firebase App Hosting Global CDN
2. Security & Identity
Firebase Authentication coupled with custom JWT claims to enforce multi-tenant isolation, role switching (Administrator vs Co-Owner), and session security.
Firebase Auth Custom JWT Claims RBAC MFA Enabled
3. Compute & Microservices
Cloud Functions v2 running on Google Cloud Run containerized infrastructure. Event-driven triggers handle file uploads, invoice OCR triggers, and automated notification dispatches.
Cloud Functions v2 Cloud Run Node.js / TypeScript EventArc Triggers
4. AI & Document Intelligence
Google Vertex AI integration (Gemini 1.5 Flash/Pro) utilizing structured JSON output schemas to parse unstructured invoices, extract IBANs, match line items, and power the resident AI assistant.
Vertex AI Gemini API Structured Output Schemas Multimodal OCR
5. Persistence & Storage
Cloud Firestore NoSQL database utilizing hierarchical tenant sub-collections and strict security rules. Encrypted Cloud Storage buckets preserve PDF contracts and expense receipts.
Cloud Firestore Cloud Storage AES-256 Encryption Firestore Rules v2
