Freelancer profile translated to English.
Back to original languageAbout Mathias
I transform struggling teams into delivering teams.
On my last long-term assignment in a multi-train SAFe financial sector environment, I took over a 9-person squad with strong cultural resistance to agility, with a sprint completion rate of 40-50%. Within one increment: 92% average, +115% velocity, PI predictability nearly double the train's average. I adapted a tailor-made estimation method adopted by the program's 7 teams, still in use after my assignment.
Before that: transformation of a SAFe train of ~80 people facing resistance (IMSA), crisis mission at Airbus, coaching a digital e-commerce transformation across 3 simultaneous teams (Manutan). Different contexts, the same method.
What I bring differently:
- A Front-End developer background (React, Vue.js, TypeScript, Azure) that allows me to speak the same language as tech teams and gain their trust quickly
- A posture of managerial courage: I defend Agile practices against management and IT when necessary
- Concrete integration of AI (Claude AI) into my practice: User Story optimization, metrics analysis, workshop preparation, capacity planning
8 years of experience in Agile environments, multi-train SAFe in banking, fintech, e-commerce, and industry. I am looking for assignments where agility needs to be built or transformed, not just maintained.
