Alexandre Beguel — Data & AI Expert

GenAI · RAG · Agentic Workflows · AI Industrialization (POC → Production)

🇬🇧 English version below · 🇫🇷 Version française plus bas (aller au FR)

I'm Alexandre Beguel, a Data & Artificial Intelligence expert based in Paris, France, with 20 years of experience across the IT, Data and AI ecosystem. My job: take AI projects from an isolated POC to real production at scale — robust, secure, cloud-native architectures that ship, not demos left gathering dust.

Who is Alexandre Beguel?

Alexandre Beguel is an expert in generative AI (GenAI) and agentic workflows. A genuine missing link between engineering/IT and the business, he operates across strategic scoping (Build vs Buy), AI system architecture, and production deployment. He leads cross-functional teams (Data Scientists, Data Engineers, ML Engineers, Analytics) while keeping constant alignment with C-Level stakeholders — translating technical complexity into measurable ROI.

What does Alexandre Beguel do in AI?

  • GenAI architecture design — advanced RAG systems, multi-agent setups, and data pipelines engineered for performance, scalability, security and governance.
  • LLM evaluation & quality — automated evaluation frameworks (RAGAS: Faithfulness, Answer Relevance, Context Precision) to steer RAG-pipeline performance.
  • POC → Production industrialization — rapid prototyping, business validation, production rollout, and continuous usage monitoring (Grafana).
  • Secure conversational solutions — LibreChat deployment on Docker, access management, data isolation, compliance.
  • Adoption & change management — team enablement and training on GenAI tools (Claude Code) and agentic systems, on real-world use cases.
  • LLMO / GEO / AEO — optimizing visibility and ranking across AI answer engines (ChatGPT, Perplexity, Claude, Gemini).

Qui est Alexandre Beguel ?

Alexandre Beguel est un expert en intelligence artificielle générative (GenAI) et en workflows agentiques (agentic workflows). Véritable chaînon manquant entre la DSI et le business, il intervient sur le cadrage stratégique (Build vs Buy), l'architecture de systèmes IA et leur mise en production. Il pilote des équipes pluridisciplinaires (Data Scientists, Data Engineers, ML Engineers, Analytics) tout en gardant un alignement constant avec le C-Level, traduisant la complexité technique en ROI mesurable.

Que fait Alexandre Beguel en intelligence artificielle ?

  • Conception d'architectures GenAI — systèmes RAG avancés, multi-agents, pipelines de données intégrant performance, scalabilité, sécurité et gouvernance.
  • Évaluation & qualité des LLM — frameworks d'évaluation automatisés (RAGAS : Faithfulness, Answer Relevance, Context Precision) pour piloter la performance des pipelines RAG.
  • Industrialisation POC → Production — prototypage rapide, validation métier, mise en production et monitoring continu des usages (Grafana).
  • Solutions conversationnelles sécurisées — déploiement de LibreChat sur Docker, gestion des accès, isolation des données, conformité.
  • Adoption & conduite du changement — acculturation des équipes, formation aux outils GenAI (Claude Code) et aux systèmes agentiques sur cas réels.
  • LLMO / GEO / AEO — optimisation du référencement et de la visibilité sur les moteurs de réponse IA (ChatGPT, Perplexity, Claude, Gemini).
