About Xavier

AI Product Lead | Product strategy, delivery & architecture | Rapid prototyping (vibe coding) | Scale & governance

Hello, I am passionate about transforming fuzzy topics into deliverable products: framing, roadmap, trade-offs, delivery, and launch.
My advantage: I combine program management, product culture, and the ability to rapidly prototype with AI (vibe coding) to accelerate field validation and reduce risk.
I work with executives, CIOs, product managers, and tech teams on: MVPs, redesigns, industrialization, and useful AI integration (not gadgets).

What I deliver concretely

  • Product strategy: discovery, framing, value proposition, roadmap, prioritization (RICE/WSJF), KPIs
  • Delivery / Program: planning, risks, governance, multi-team coordination, budget & performance management
  • Vibe coding: clickable prototypes / POCs / MVPs (Next.js / Expo / Supabase / FastAPI, etc.) for quick validation
  • Pragmatic architecture: APIs, data model, RLS/permissions, scalability, observability, controlled technical debt
  • Applied AI: internal assistants, workflows, RAG, automations, business copilots (with security safeguards)
