ABOUT
Product Designer with 10+ years working across the entire lifecycle of digital products — from discovery to delivery and continuous iteration. I specialize in complex platforms like management systems, backoffice tools, mobile apps, and B2B/B2C solutions.
Experienced collaborating with international teams in multicultural contexts. I conduct qualitative and quantitative user research, plan and execute usability tests, and create flows, wireframes, and high-fidelity interfaces focused on clarity, consistency, and accessibility.
Strategic mindset focused on results — aligning user experience with business goals. From facilitating co-creation workshops to building design systems for scalable products, I bridge the gap between design and engineering.

WORK
HISTORY
Product Designer
Enhance Fitness
Leading the redesign of a fitness SaaS platform based in Dubai, with users across the Middle East and the US. The platform had grown fast but accumulated inconsistent patterns between modules — standardizing flows and raising usability across the product became the central design challenge. The process starts with discovery: stakeholder sessions and user interviews to map where the experience breaks down. From there, qualitative research, usability tests (both remote and in-person), wireframes, and high-fidelity interfaces aligned with the product's design system. Generative AI is part of the prototyping workflow — used to validate layout hypotheses faster before committing to polished designs. Beyond screen-level work: documenting business rules for the dev squad, facilitating co-creation sessions across Product, Design, and Tech, and tracking post-launch metrics to inform the next iteration cycle.
Product Designer
Zup Innovation
Seven years designing for major Brazilian financial institutions — Itaú, Santander, Banco ABC Brasil, and Banco Pine — across products ranging from rural credit platforms to mobile payments to hospital management systems. Each project demanded a different approach. For Itaú Agro, the challenge was making complex credit and loan workflows navigable for agribusiness clients. With iti Itaú, the focus shifted to proximity sales: a mobile-first payment product aimed at small vendors and informal businesses across Brazil. At Gerando Falcões, an NGO in low-income communities, field research happened where digital adoption was minimal — the kind of context that tests whether design assumptions hold outside controlled environments. Other projects included integrated backoffice systems for Todos Pela Saúde (a healthcare initiative during the Covid-19 pandemic) and internet banking platforms for Banco ABC Brasil, Banco Pine, and Santander Brasil. Across all projects: discovery with users and stakeholders, flow and wireframe definition, reusable component design, documentation for dev handoff, and usability validation. Worked in multidisciplinary squads and collaborated closely with engineering and architecture teams to ensure technical feasibility.
Art Director
P Comunicação
Art direction for digital marketing and inbound campaigns — from concept through final delivery. The work centered on web interfaces and visual assets (landing pages, email sequences, social media content) designed around conversion goals, not just aesthetics. Daily collaboration with copywriters, planners, and developers, maintaining visual and strategic consistency across channels while meeting performance-driven targets.
Customer Success
Wik Agency
Social media strategy and client management at a digital agency, acting as the primary bridge between clients and the creative team. The role combined campaign planning, content coordination, and performance tracking — with hands-on adjustments to tactics based on engagement data and client feedback.
