About Gabin

I bring your SaaS products and AI systems from experimentation to reliable, scalable, and cost-controlled production.

Co-founder and CTPO of Justiana (legaltech SaaS for employee representatives): I designed and led all tech — architecture, sovereign multi-model RAG stack (Mistral, Gemini), Kubernetes deployment, 100+ releases in 6 months, in a sensitive data context. Before that, critical legacy modernization (Java / Spring Boot, DDD / CQRS) and AI product design for legal and HR.

What I do for you:
— Architect and deliver SaaS that scales and lasts
— Integrate a useful and reliable AI layer (RAG, multi-model orchestration, agents) without exploding the LLM bill
— Act as CTO / technical lead on your strategic topics

My conviction: a system is judged in production, not in demo. Craftsmanship, TDD/BDD, clean architecture: not by dogma, but because it's what keeps a product (and its AI layer) maintainable and prevents it from collapsing six months later.
