About Julien

My expertise combines needs analysis, advanced AI architecture, and LLMOps.
I design AI solutions truly adapted to your context: intelligent agents, robust automations, optimized workflows, and integration into your business tools.

Beyond development, I provide real strategic support:
Precise needs and ROI analysis,
Choice of optimal architecture,
Complete LLMOps (monitoring, testing, security, observability),
Reduction of LLM costs through caching, prompt optimization, orchestration, and best practices.

My goal: to deliver a solution that is not just "functional" but performant, scalable, and profitable, with clear follow-up from start to production.
