Senior Designer | Data-Informed | Business-Minded
Leonardo Acero
I’m a senior product designer with 10+ years of experience crafting intuitive, high-impact digital products across mobile and web. I specialise in simplifying complex challenges through design—delivering solutions that are as commercially effective as they are user-centric.
I lead end-to-end product design grounded in research, guided by data, and aligned with strategic goals. My work sits at the intersection of usability, scalability, and business value.
Core strengths:
🔍 Full ownership of the design process—from discovery to delivery.
📈 Data-led UX: A/B testing, analytics, and behavioural insights to drive outcomes.
🧱 Scalable design systems ensuring speed and consistency across platforms.
🤝 Deep collaboration with engineers, PMs, and C-level stakeholders.
🚀 Product features that have driven over 30% increases in retention and engagement.
I hold an Italian passport and permanent UK residence, and I’m open to remote or hybrid roles across the UK and Europe. Bilingual in English and Spanish, I bring a clear, focused, and outcome-driven design approach to every team I join.
