--- title: "Background — Sébastien Soulier" description: "25+ years in information systems, from Accenture to Infomil: experience, skills, training." canonical: https://www.sebastiensoulier.com/en/about author: "Sébastien Soulier" language: en dateModified: 2026-09-25 --- # 25+ years in information systems 25+ years designing, leading and delivering demanding IT projects, from development to project leadership. My time at Accenture, Logica, Frequentiel, Air Cost Control, Sopra Steria and Infomil gave me a cross-cutting view of the information system: from infrastructure to application, from strategic framing to go-live. I started my business in May 2026 to put this experience at the service of SMEs, local authorities and small businesses in the Gers and the Toulouse area: choosing their tools, making their data flow, and bringing in AI where it really helps. -
