About Marion

My DNA: User success above all

My nearly 3 years of experience at Trackdéchets (a state startup) allowed me to develop expertise in User Success and actively participate in the product approach, thanks to:

**- Onboarding & Training**: Creation of tutorials, FAQs, and training workshops to facilitate platform adoption (companies, local authorities, administrations).

**- Support & Assistance**: Ticket management via Zammad, agile incident resolution in coordination with internal teams (Tech, Product).

**- Communication**: Targeted emailing campaigns (Brevo) and automated follow-ups, community management on LinkedIn, and YouTube account management to reinforce adoption.

**- Data-driven Management**: KPIs (adoption, retention, NPS) via Metabase, Plausible, and feedback loops to continuously adjust processes.

**- Project Management & Product Quality**: Feature specification, bug reporting and tracking, writing test cases to validate developments.
**- Coordination & Cross-functionality**: Facilitating collaborative workshops (Miro, Notion), weekly syncs, participation in sprint/testing launches.

Skills & Tools

- User Success: onboarding, customer support, retention/upsell campaigns, KPI management.
- Marketing & Communication: Facebook/Instagram Ads campaigns, storytelling, visual creation (Midjourney, ChatGPT, Canva, Figma), performance analysis (Google Analytics, Plausible).
- Product: spec writing, testing, backlog prioritization, Tech/Product coordination, bug management (Zammad).
- Agility & Organization: Scrum/Kanban, Trello, Miro, Notion.

Why work together?

- Marketing vision: storytelling and performance.
- Product approach: currently training as a Product Manager (OpenClassrooms), graduating in the coming months.

Trackdéchets

Reviewed on 10/22/2025

A big thank you for the work accomplished by Marion in the implementation of the dematerialization of hazardous waste traceability and the integration of the National Register functionalities, nationwide, since June 2022. Her commitment has led to wide recognition from industry stakeholders and has contributed to making Trackdéchets an innovative public project, emblematic of "state unicorns". As a User Success professional, Marion actively contributed to the project's success by supporting users (Trackdéchets: 428,000 users), facilitating the adoption of practices, and implementing targeted communications and training, always focused on the satisfaction of stakeholders in the waste ecosystem. It is a real pleasure to work with Marion, who is autonomous and driven by great motivation.
