Cover image for Redesigned the full courier app
Redesigned the full courier app for Glovo, transforming a complex multi-delivery workflow into a simple, intuitive experience used across 14 countries. The product handled real-time task assignment, route navigation, and delivery status across millions of daily deliveries. The project started with user research across multiple markets to understand how couriers were actually working and where the flow was breaking down. From that I defined the product direction, redesigned the full UX from task assignment to delivery completion, and coordinated 14 engineers across 3 squads from discovery to launch. Reduced average task completion time by 3 seconds per delivery, generating €2K per month in operational efficiency gains.

Cover image for Led the go-to-market and product
Led the go-to-market and product execution for e-invoicing launched simultaneously across Germany and Spain, meeting a hard EU regulatory deadline. Defined the value proposition for non-expert users navigating complex tax and invoicing requirements, redesigned the onboarding flow to reduce time to first value, and unified the payment architecture across both markets. Contributed to 8% customer acquisition growth.

Cover image for Lumen AI School is an
Lumen AI School is an academy teaching kids how to use and understand AI tools. I built the full product and executed the go-to-market from scratch. On the growth side I designed and ran a 5-day acquisition sprint to get first students fast. The strategy prioritised the highest-converting channels first: personalised outreach to old leads, WhatsApp messages to the personal network, Facebook parent groups, a demo event on Sympla, and direct emails to school directors. All five converted within the first week without any paid advertising. Longer term channels, like Instagram, YouTube, SEO, and formal parent workshops were built in parallel as the student base grew.

Cover image for NutriPup is an AI-powered mobile
NutriPup is an AI-powered mobile app that helps dog owners feed their dogs with confidence, with personalised nutrition guidance at a fraction of the cost of a veterinary nutritionist. Started with user research across 312 dog owners in Brazil and Spain to validate the problem and define the value proposition. Designed the full product experience, built and shipped the app to both the App Store and Google Play in 3 weeks, with in-app purchase integration approved on both platforms.
