Designer building products and experiences with code and AI for 9+ years.
Open to work. Full-time or freelance.
Coisas.space
Coisas.space is a product that uses AI to categorize every saved link and let you chat with what you've saved, to actually learn from it. Matching is semantic: ask about React and it surfaces links that never mention React in the title. I used AI across the whole process, from research to ideation to testing.

Atri
AI-powered health service that helped people with type 1 diabetes stay in healthy glucose levels 4x longer. The hardest design problem was the failure mode: fallback flows for low-confidence model readings, progressive disclosure of uncertainty, and trust recovery patterns so silent failures never broke the user's confidence in the system.

Winnin
Winnin is an audience intelligence platform. Coca-Cola, Samsung, and Meta are among the brands that use it. I started as Senior Designer and got promoted to Design Coordinator after leading discovery. I bet on dashboards by use case and shipped Zai, a conversational AI that builds brand territories. Engagement doubled and ARR went from $2M to $8M in two years.

Eva
Eva is an HR tech platform for employee onboarding journeys. I was Founding Designer and built a content creator and a journey builder, so HR teams could plan communication while AI and Eva's bot ran the whole journey. We hit R$100k MRR in 6 months, and in a year we had 40+ clients with a 9.1 NPS.
2023
I'm a Product Designer and Design Engineer with 9+ years building products from 0 to 1 in early-stage startups and scale-ups, the last 6 focused on SaaS, B2B, B2B2C, and AI-first. I've built and led design teams, and for those same 6 years I've been mentoring designers on UX, leadership, strategy, and UX engineering.
My work with AI has been at the business, product, and experience layer: from choosing ML models to using AI in the design and build process itself, and in products where AI was the core value delivered. In technical terms:
Conversational & generative AI: Built a Brand & Culture agent at Winnin, NLP over data with Wilson, RAG agents at Resense, and a nutrition assistant at Atri.
ML confidence & uncertainty as UX: Translating clinical risk in glucose readings and insulin dosing at Atri, helping turn probabilistic output into decisions and care.
Classification, clustering & recommendation: Territories and video recommendation in audience intelligence at Winnin; content categorization and recommendation at Coisas.space.
Prediction & ranking: Failure prediction and equipment-replacement prioritization by ROI in predictive maintenance, and real-estate valorization at Oncase.
AI-native tooling: Agents, subagents, skills, agent-ready component libraries; AI tools (Cursor, Claude Code, Antigravity), tooling-agnostic.
