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.
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.
