PropTech platform for real-estate asset management, documentation, certificates, and financial and environmental analysis, with AI agents, RAG and n8n automations.

Summary
PropTech platform for real-estate asset management, documentation, certificates, and financial and environmental analysis, with AI agents, RAG and n8n automations.
My participation
Led the technical development of the platform across frontend, APIs, authentication, buildings and digital books, Supabase and deployment. Also built n8n workflows for classification, document validation, and financial and environmental agents.
Implementation
I worked across a React/TypeScript frontend and Node.js/Express backend using Supabase, PostgreSQL, storage and RLS. I also orchestrated Redis/BullMQ processes and n8n webhooks for query classification, file validation, and OpenAI/Supabase coordination.
Artificial intelligence
Designed and integrated workflows that validate PDFs and images, apply checklists, detect duplicates and store results in Supabase. I also implemented financial and environmental RAG flows with OpenAI embeddings, Supabase Vector Store and specialized agents, plus a webhook-based query classifier.
Result
The platform centralizes buildings, documents, audits and finance, with automation for validated ingestion and contextual retrieval of financial and environmental information aligned with European regulations.
