What I'm looking for

I’m looking to design end-to-end AI-powered fintech and conversational products in fast-paced teams—owning discovery through launch, building scalable design systems, and partnering closely with PMs and engineering. Open to remote engagements globally.

I design financial and AI-powered products that handle real user transactions, serve tens of millions of users, and ship inside fast-paced cross-functional teams. With 10+ years of end-to-end product design across fintech, insurance, and conversational AI platforms, I bring UX strategy, UI craft, and product thinking together to deliver work that’s both elegant and measurable.

My approach is built on end-to-end ownership—from discovery workshops and user research through Figma prototypes, design systems, and post-launch iteration. I specialize in AI-powered product design (conversational flows, agentic interfaces, NLP-driven UX), using AI tools daily to prototype faster and explore interaction patterns with speed.

I also lead at the systems level: token-based architectures, MFE component libraries, and cross-platform design systems (web, mobile, Unity) designed for long-term consistency. I’ve delivered proven impact such as R$1.4M revenue recovery, 38% customer retention, 20% conversion uplift, and 30% dev time reduction, while collaborating closely with PMs, engineers, and business stakeholders to shape roadmaps with evidence-based storytelling.
