Want to move from AI PoC to production? I design and deploy reliable generative AI systems on GCP: RAG pipelines, LLM integration and data pipelines, backend APIs (FastAPI), observability (Langfuse), and evaluation.
Concrete results:
- Data pipeline including LLM extraction with evaluation on +18k real estate ads and semantic matching score (Vertex) on almo.fr
- AI legal chatbot in production, first Google page on target queries (robindesdroits.com)
- RAG pipeline < 2s latency, hallucination rate reduced by 18%
- Payment infrastructure $700M+ (Request Network, YC W17)
Currently fractional CTO at Almo (PropTech AI).
9+ years of experience, from data science to GenAI in production. GCP Certified Cloud Architect.
