Transformer ses équipes IT en développeurs augmentés - Guillaume Galasso, DSI SERGIC

A migration estimated at 10 days, completed in an afternoon with Claude Code. Guillaume Galasso, CIO at SERGIC, transformed the way his developers work using AI, and he explains everything in this episode. In 2020, he took over an IT system built in 1973. Efficient, but complex and aging. His mission: to oversee the reconstruction as efficiently as possible, without ever interrupting operations. Once the foundations were laid, he integrated AI into the daily work of his development teams. The result: developers working 5 to 10 times faster. In this episode, Guillaume shares his method and his vision of the AI-enhanced employee. 00:00 Intro 00:53 Sergic - Group Presentation 01:31 IT system created in 1973 02:31 Why the system lasted 50 years 03:22 The limitations of legacy systems 10:01 Transformation strategy - new skills 11:39 Debate: Commercial vs. custom ERP 14:06 Results - production February 2025 16:01 Arrival of AI (2023) - Power Automate + OpenAI 18:25 How developers work with AI (Claude Code and Cursor) 19:06 Vibe coding vs. agentic coding 24:23 Managing AI, agents with sub-agents 25:53 Business case: Companion application 29:11 Lessons learned after 4 years 33:39 Why he would do things differently today 54:09 CIO vision in 5 years Guillaume Galasso on LinkedIn:   / guillaume-galasso-8966741   SERGIC:   / sergic   Wintalk is brought to you by Winside, an IT services company structured around six specialized subsidiaries: Infrastructure, Development, Product & Project, Cybersecurity, Data, and Finance.
