Antonin Crestois

Solutions Architect
CRM Architecture, Integrations & AI

I work on turning complex customer challenges into practical, high-impact solutions across CRM, AI, automation, reporting, and systems design.

My focus is helping teams move from unclear requirements to concrete roadmaps, scalable implementation plans, and measurable business outcomes.

This site is a small place for my resume, project notes, and writing about agentic workflows, customer systems.
