I am Luiz Felipe
I turn user research into interfaces that convert — 7 years, 3 countries, 20+ products.

Nice to have you here!
Welcome

I grew up in São Paulo, spending weekends at my uncle's — a software developer who sparked my curiosity for tech. From anime-inspired sketches to a degree in Information Science at USP (2018), I learned early that creativity and information are inseparable.
In college, I co-founded the first student center in my program and built websites for the community. Today I am a Senior Product Designer at Mercado Pago, building a subscription platform used by thousands of clients.
"Luiz is a person who is always willing to help and set the example of good execution and passion for what he does. He is a reference in terms of design and always asks the right questions."
— Ramiro Paz, Product Manager
