Are you a director or head of a department in your company and wish to be supported in the launch of a new product or service and/or in the growth of your revenue via the Internet?

I offer profitable digital strategies and execute them for you in record time.

Some recent examples:

    Ozeo.io is an expert digital marketing agency and one of the first Hubspot partner agencies in France. Intensively trained for 2 years by the CEO of Ozeo.io agency since its inception, I have successfully led over a dozen innovative projects in French and English for large corporations, SMEs, and small businesses.


    I justified my strategic proposals to management teams and reported on my actions and results weekly.

    I defined and executed customer acquisition strategies for the Ozeo.io agency and its clients.

    I directed development, graphic design, and consulting teams in French and English.

    I managed and planned projects for the agency and its clients on Jira Atlassian and Asana in French and English.

    I coached and trained sales teams on Hubspot CRM in person.

    I created online audiovisual training courses in digital marketing with a member area for clients to make them autonomous on the tools.

    I trained Ozeo.io agency consultants on the best existing webmarketing techniques, and they are now leaders in digital marketing.

    I created processes and systems for the agency and its clients that boosted the productivity of Ozeo consultants. Some examples:
    - Meeting procedure with an agency client.
    - Onboarding and weekly client follow-up procedure from start to finish.
    - Procedure for a landing page that converts
    - Procedure for an advertisement that converts
    - Procedures for using each tool used by the agency.

    SGS is the world leader in inspection, verification, testing, and certification, recognized as the global benchmark for quality and integrity.


    I had a consulting role in the Management Committee and managed 4 international digital marketing projects on JIRA.

    I provided daily reporting of actions and results and weekly reports to the management committee, both written and oral in English, in which I justified my strategic choices.

    I implemented real-time reporting for Google Ads, Google Display, Google Shopping, LinkedIn Ads, and Facebook Ads campaigns in French and English using Zapier.

    I successfully led an MVP GDPR marketplace project in 8 weeks which generated an advertising ROI of x13.5 for the SGS France group.

    I defined and implemented email and marketing automation campaigns on ActiveCampaign and Oracle Eloqua for SGS Europe, generating a 32% growth in customer acquisition conversion rate.

    I created Zapier API workflows between the SalesForce CRM, ActiveCampaign, and Google Sheet to break down data silos.

    I analyzed user behavior of visitors on pages with Hotjar and conducted A/B Testing to continuously optimize campaigns.

    I implemented pixels, scripts, and advertising tracking with Google Tag Manager to remain GDPR compliant and optimize advertising efforts with retargeting.

    I created, managed, and performed A/B testing on French and international landing pages (Unbounce, HTML, CSS, JavaScript).

    I trained and coached SGS France sales teams in person on prospecting using LinkedIn Sales Navigator.
