Welcome 👋

I am currently CTO AI Modernisation at Theodo, helping CTOs modernise legacy applications 3x faster with AI.

Have a legacy application to modernise?
Contact me at quentin.pleple@theodo.com

I am excited about AI coding assistants, modernising old systems, Lean methodologies, and LLMs and how they work internally.

Before that, I was Lead Generative AI Architect at Reverso for 2 years, and worked 14 years at Short Edition as co-founder and CTO. I studied at Polytechnique (France) and UCSD (California).
