About Benjamin

Scrum Master / Product Owner (3 years) – Paris (hybrid)
Certified PSM1 Scrum Master, I support teams in implementing and structuring agile frameworks adapted to their maturity level. I am involved in facilitating rituals, optimizing workflow, managing dependencies, resolving technical obstacles, and improving the quality of deliverables.

Accustomed to complex environments (SaaS, API, data, distributed architectures), I collaborate closely with developers, QA, UX, and technical experts to streamline interactions and ensure stable and predictable delivery. I rely on metrics (velocity, cycle time, burndown, quality) to track progress, identify friction points, and adjust practices.

Coaching-oriented, I help teams strengthen their autonomy, decision-making ability, and understanding of the Scrum framework. I train POs and teams on best practices, assist with prioritization, clarify roles, and establish a sustainable culture of continuous improvement. My experience in Product Ownership also allows me to facilitate the link between product vision, business needs, and technical challenges.

**My goal**: to create a pragmatic, effective agile framework aligned with objectives, to help teams deliver value regularly and with confidence.



**Conditions**: Paris / Île-de-France, hybrid format (in-person + remote).

I conduct my independent activity through a payroll company.
Administrative aspects (invoicing, contracts, professional liability insurance) are managed by my payroll company.


Let's discuss your context: I can audit your backlog/rituals and propose a rapid impact plan.
