About Vianney

With 8+ years of experience in Customer Success, Project Management, and SaaS Implementation, I help companies deliver successful projects and build lasting client relationships.

My profile is hybrid by design: I understand the business priorities of decision-makers, the technical constraints of engineering teams, and the real expectations of end users. I manage projects end-to-end — from scoping to go-live — keeping adoption, satisfaction, and ROI at the center of every decision.

I founded EmailSortPro, a full API product integrating Gmail and Outlook, which deepened my hands-on expertise in architecture, automation, and AI integration (Claude, ChatGPT, n8n, Lovable).

What I bring:
• AI Optimisation
• Customer portfolio management
• End-to-end implementations and projects from €5k to €50k
• 94% active adoption rate achieved post go-live on a critical CRM rollout
• Full-stack project ownership: scoping, stakeholder mapping, KPIs, governance
• Strong AI & automation skills applied to real product workflows
I'm currently open to CSM, Project Manager, Implementation Consultant, or Pre-Sales Engineer roles — ideally in a SaaS or tech environment. Feel free to reach out directly.
