À propos de Hadrien
Software Engineer / AI Architect
Software engineer with 16+ years of experience designing and delivering complex digital systems in production environments.
I specialize in AI architecture (LLM strategy, RAG pipelines, vector databases, governance, cost control) and scalable SaaS platforms. I design and deploy multi-tenant, secure, high-performance systems from architecture to production.
My expertise spans:
AI systems in production (RAG, embeddings, multi-LLM orchestration, observability)
Backend architecture (Ruby on Rails, Python/Django, PostgreSQL)
DevOps & cloud deployment (Docker, CI/CD, AWS, Azure, Scalingo)
Performance optimization and system refactoring
Technical leadership, mentoring, and architectural decision-making
I operate across the full software lifecycle: audit, system design, development, infrastructure, and long-term maintenance.
I also build and operate my own SaaS products (AI chatbot, educational platform, booking & payment system), combining product thinking with strong technical execution.
