About Reto

Hey, I'm Reto.

After studying psychology, I could have gone the traditional route into therapy. I consciously chose e-commerce because the crucial question grabs me: Why does someone click "Buy" and why not? That's applied psychology, just with immediate measurable results.

And then there's AI. In my opinion, hardly any topic is changing marketing as fundamentally as AI right now, and I don't want to just watch; I want to be at the forefront. **I develop advertising videos entirely on my own using AI**: concept, image generation, animation, voiceover, editing. At the same time, it's important to me to use AI responsibly. That's exactly what I wrote my bachelor's thesis about: an acceptance study on AI chatbots in psychotherapy (grade 1.3).

Since the beginning of the year, I have beenmanaging a German Amazon Selleras a freelancer. I create listing images and A+ Content, conduct A/B tests, and produce AI advertising videos directly in the client's Seller Central. Product development has also become part of my tasks, from the idea to preparing for sourcing.

I also have experience in research: For one year, Iconducted user interviews and moderated usability testsfor a client. Listening, asking follow-up questions, understanding needs – these are skills from my psychology studies that no AI can replace.

I work flexibly and remotely, in German and English. Just send me a message, and we'll see if it's a good fit.

    January 2026 - Today (6 months)
    Karlsruhe, Germany
    Since the beginning of 2026, I have been managing the marketing for a German Amazon seller in the board games sector – now over 230 hours, with direct access to Seller Central.

    I revise listing images and A/B test them against each other, create A+ Content, and produce advertising videos entirely myself: script, AI-generated visuals and animation (Kling, GPT Images), voiceover (ElevenLabs), editing (CapCut). All content is created directly in German, not as a translation.

    For several months now, I have also been involved in the development of a new product together with the client's graphic designer – my first insight into product development and sourcing on the manufacturer's side.
    The collaboration has been ongoing for over a year.

    – Amazon Listing Optimization & A/B Testing
    – A+ Content
    – Advertising Video Production (AI Pipeline, End-to-End)
