Tech-Agnostic by Design → The need defines the tech. Not the other way around.
I design and deploy Generative AI systems tailored for production: robust, secure, compliant. From RAG pipelines and LLM orchestration to multi-agent agentic architectures, I cover the entire chain, from prototype to production.
Why me?
- Tech-Agnostic: The right tool for the right need. Zero dogmatism.
- Dual expertise: Advanced LLMs (Python, advanced prompt engineering) + high-performance engineering (Rust, Go, Kubernetes, AWS).
- Digital Sovereignty: FR + EU First, GDPR, SecNumCloud, HDS compliance.
- DevSecOps Mindset: CI/CD, testing, containers.
