Julien Taste

Cloud & AI Architect · 15+ years of experience · AWS, Azure, GCP

I help organizations get the most out of their cloud infrastructure while mastering costs, security, and AI projects. My background covers banking, insurance, defense, automotive, and industry.

ㅤ

▸ Cloud & FinOps

Design of large-scale multi-cloud architectures. AI-enhanced FinOps strategies: predictive cost analysis, automatic rightsizing, optimization without sacrificing performance.

▸ Generative AI — from POC to production

Agentic RAG architectures, multi-agent systems (Google ADK, PydanticAI, LangGraph), deployment on Amazon Bedrock and Vertex AI. An AI system that works in demo is not an AI system that works — I ensure it holds up in production.

▸ Cybersecurity & Compliance

Hybrid SOCs (Wazuh, Elastic Stack, OpenTelemetry), Zero Trust, ISO 27001, SOC 2, AI Act compliance. Environments where security is non-negotiable.
