- Leading the Experimentation and Communications tribes, composed of cross-functional teams covering Engineering (Data, Backend, Frontend, Mobile) and Data Science. I work closely with the Product leadership team and stakeholders to define the long-term vision and strategy for both domains, including product and technical perspectives.- The Experimentation tribe provides teams across HelloFresh with a powerful experimentation platform that enables thousands of experiments annually, from digital product to marketing. I initiated and led the evaluation of external platforms to address capability gaps in our in-house solution. The vendor evaluation and as well as the migration to our chosen vendor were completed in under 12 months, allowing the first teams to run experiments on the new platform within 6 months.- The Communications tribe offers HelloFresh a scalable Marketing Technology platform for reaching customers and prospects through their preferred channels (email, mobile, in-app, SMS, etc.). The teams support both operational and marketing use cases, manage all integrations with external vendors (e.g., Mobile SDKs), and run hundreds of data pipelines every day. These pipelines provide data for personalized customer communications and insights into channel performance and health.
