Designing digital products for 10+ years, Born in Rio, Based in Lisbon

Lui Spadarotto, Product Designer

I’ve designed products across mobility, fintech, healthcare, and AI — from early-stage startups to large-scale platforms. Today, I’m building Roopzy, a scheduling tool for small business owners, and working at Kaizen Gaming on payment experiences used across multiple markets.

I think in systems, ask a lot of questions, and design with care, so people don’t have to overthink what should feel simple. I believe clarity is a form of respect, and that good operations support good design.

I was born in Rio de Janeiro (RJ) and raised in Baixada Fluminense, witnessing my parents' journey from hardship to success. Unfortunately, I had a difficult relationship with them, especially my progenitor, who was often aggressive. At 20, I left my progenitor home in Vila Velha (ES) with 500 reais and moved to São Paulo (SP) with two friends I met online. Thankfully, they turned out to be wonderful people who supported me.

In São Paulo, I had the opportunity to grow professionally and meet incredible people who helped me along the way. In late 2019, I moved to Portugal, currently in Lisbon, where I continue to build my life with my chosen family (my friends), my three cats, who came with me from São Paulo, and my partner.

During my childhood, I moved around a lot due to the fact that my parents were in the military.

Lui was part of one of my teams where she played a great role in the bank's main product. She was always very curious, close and connected with the team, she was always looking for solutions and the best way to design and defend her points of view.

Her great qualifications are linked to UX and UI design, motion design, organization of complex contexts, among others. Always happy and with a smile on her face, she infects the team with a good culture of sharing. I would like to have her on my team again.

As a Product Designer, she was able to analyze the journey of gas station users and propose solutions to improve the customer fueling experience here in Brazil, showing seniority through all stages of the project. She also created data monitoring panels and a performance monitoring tool for each of our retail partners, that were highly praised by everyone in the company.

It would be a pleasure to work again with Lui on any project.
