Freelancer profile translated to English.
Back to original languageAbout Alexandre
I help companies automate their processes and unlock the value of their internal documents with AI.
I design systems combining n8n (workflow orchestration) and RAG pipelines — enabling companies to automatically answer questions about their own documents, process incoming emails, trigger actions from real-world events, and much more. All self-hosted, without SaaS subscriptions.
What I bring:
- RAG pipelines on private documents (LlamaIndex, ChromaDB, Cohere, Claude API), evaluated with RAGAS (Faithfulness 0.91, Context Recall 0.93)
- n8n automation: email triggers, webhooks, API integrations, Gmail, scheduling
- Solid backend foundation: 8+ years in Java/Spring Boot, Angular, REST APIs — in production at IATA, GovTech vaudois, and EDF
Available 4 days/week, fully remote or in-person in the PACA/Hautes-Alpes region.
