Hi, you can call me May!
I’m a brazilian Senior Product Designer who loves turning messy, high-stakes problems into clear, confident experiences for people and businesses. Over the last 5+ years, I’ve designed for financial services, B2B SaaS and marketplace, from investment products at Latin America’s largest bank to crypto wallets in Uruguay and workflow tools for logistics and marketing teams across the Americas.
My path into product wasn’t linear. I started in spatial and visual design, moved into marketing, then ran my own vegan cosmetics brand for four years. That experience of owning a business end-to-end (understanding customers, building a brand, watching metrics, and making hard trade-offs) is still the backbone of how I design today: every screen has to make sense for the user and for the business.
Today, I work mostly in FinTech and B2B platforms: investment journeys, digital wallets, accounts-payable automation, and internal tools that sit on top of complex rules, regulations and data. I’m comfortable in environments where there are many stakeholders, constraints, and edge cases, and where clarity is the main value you can deliver.
My way of working is very structured and pattern-oriented. I tend to zoom out first (mapping systems, constraints and risks) and then zoom in with rigorous discovery (interviews, surveys, analytics, complaint analysis, opportunity trees, impact/effort matrices). From there, I translate insights into journeys, flows and design systems that teams can actually implement and scale. People usually trust me with the most complex discoveries, the ones that require connecting many data sources and perspectives at once and turning them into something tangible: clear journeys, priorities and a roadmap the team can actually execute on.
In the last few years, I’ve also been integrating AI into my practice (from deep research and data synthesis to prototyping AI-powered assistants like Guia da Bolsa, a multi-agent co-pilot for new investors). I see AI as a thinking partner, not a shortcut: something that helps me explore more options, stress-test ideas and communicate complex concepts in simpler ways.
Across all these experiences, one thing stays constant: I care about designing products that feel trustworthy, explain themselves clearly, and respect how people actually make decisions in real life, especially when money is involved.
