Back to original languageAbout Léo Clément
Do you have a product to frame, a data platform, a web or mobile application, an AI use case? A backlog to structure, a roadmap to follow in a demanding environment?
I help business and tech teams transform complex needs into concrete, deliverable, and high-impact products.
My background:
- 4 years at Sopra Steria on critical environments (Airbus, Eurocontrol), where performance and reliability are non-negotiable
- Product Owner for the Flying Green project (Eurocontrol), within a team of 10 people: scaling a data solution from 200 GB to several terabytes while making it scalable, with a successful migration from PostgreSQL to Cosmos DB
- At Airbus, implementation of team velocity tracking, which was previously non-existent, to improve planning and delivery reliability
- Product Owner and full-stack developer for Gentiris, a web platform that I took from ideation to production (front, back, infra)
- CertifiedPSPO Iand Scrum MasterSAFe 6
- Former Senior Data Engineer: I speak 'dev' (Python, SQL, Azure, Alteryx)
This dual tech and product culture allows me to challenge estimates, write directly usable specs, and identify risks early on.
What I can bring you:
- Framing and strategy for web, mobile, data, or AI products
- Backlog structuring and prioritization
- Effective interface between technical and business teams
- Improved velocity and secured production deployment
