Marketing Gun For Hire




From project lead to Head of CRM, from sales to direct marketing, I've worked in a wide range of roles in the field, with a focus on data-driven marketing in digital channels, both for customer acquisition and retention.


Having worked for companies such as eBay, HUGO both and other online retailers in the B2C space, I am deeply familiar with the specific tactics, challenges and opportunities in e-commerce marketing.


I've initiated and been part of several RFP and roll-out projects for campaigning, content management and other tools, including requirements analysis, vendor selection and transitioning.

What I can help you with

Product Owner

As a Scrum Certified Product Owner, I am well acquainted with agile methodologies, both in theory and in practice. Translating a product vision and business requirements into concrete user stories and working with the teams to realize them in order of business value.

Senior Project Manager

A hands-on, pragmatic seasoned project manager, I support you in delivering on your projects. With ample experience in the corporate world, I know to place special focus on stakeholder management, getting buy-in from senior management, managing the change involved and promoting projects within the organisation and the team.


Passing on knowledge to younger team members and supporting them in taking on more complex tasks and responsibility has always been part of my assignments, even though this may not appear in any job description. As a mentor involved with organizations such as MentorMe and TeachFirst Germany, I've always enjoyed giving back to the next generation.

Based in Berlin, Germany, I'm available for projects in Germany, Austria and Switzerland on-site and remote.
