Back to original languageAbout Christophe
I manage your projects from A to Z: strategic scoping, functional specifications, technical architecture, product backlog (user stories, acceptance criteria), Agile sprint management, and functional testing.
I have solid experience in complex environments: Business Analyst (RATP), IT Project Management (BNP Paribas Real Estate), and HRIS (ACT-ON). This 360° view of the IT value chain allows me to support startups and SMEs in their AI adoption, from proof of concept to production.
Passionate about generative AI and advanced prompt engineering (Chain-of-Thought, Few-shot, RAG, Self-critique), I have designed and delivered 5 operational micro-SaaS products in agile mode:
🔹 Zenesis, AI Agile Generator: transforms a PRD into a complete backlog (Epics, BDD User Stories, Gherkin, Fibonacci Story Points, MoSCoW prioritization, Squad roles, and Lean phases) with Jira/Linear export.
🔹 VidaCraft Studio, Pro AI Prompt Generation SaaS Platform (Packshot, Moodboard, Mannequin) integrating 50+ templates, guided assistant, Firebase authentication, and Stripe subscription tunnel.
🔹 Hook Lab, Viral Hook Generator leveraging 20 frameworks (PAS, AIDA, Pattern Interrupt, Story Hook) to produce 10 scored hooks in 5 seconds, suitable for TikTok, Instagram, LinkedIn, X, and YouTube.
🔹 Agent Maestro, Multi-agent system with local RAG architecture transforming a creative brief into an optimized prompt for image generation (Midjourney, Flux, DALL‑E) in 5 seconds.
🔹 Vidavocat, AI Legal Assistant designed for legal professionals, students, and requesters, covering 6 domains to analyze situations and guide towards appropriate procedures.
I assist startups with their AI strategy: cloud infrastructure, RAG/LLM architecture, agentic AI, and business process automation. My agile approach ensures rapid time-to-market and measurable ROI.
