Hi, I’m Lucas Dantas, a Senior Product Designer specialized in fintech, payments and merchant platforms.

Currently designing merchant experiences for Mercado Pago, the fintech arm of Mercado Libre.

Selected projects

Launcher Smart POS

Redesigning the core navigation system for merchant payment devices to improve usability and scalability.

Unified Transfers (Pix & TED)

Simplifying bank transfer flows by unifying Pix and TED experiences into a single interaction model.

Kiosk Mode – Smart POS

Designing a self-service experience for merchants using POS devices in physical environments.

Pix Key Management

Improving the management and usability of Pix keys for millions of users.

Experience

I design end-to-end product experiences focused on solving real human problems and simplifying complex workflows.

Through product discovery, research and usability testing, I help teams validate ideas and build solutions that are intuitive, scalable and aligned with business goals.

01

Product Strategy

I translate complex business and technical requirements into clear, user-centered roadmaps.

From early discovery to MVP definition, I partner with PMs and Engineers to prioritize features, explore technical trade-offs, and ensure every design decision aligns with long-term business goals.

02

Fintech & Payment Systems

I specialize in high-stakes financial ecosystems, including Pix, digital banking, and Smart POS hardware.

My focus is on simplifying mission-critical operations, ensuring that high-frequency interactions, like transfers and merchant management are reliable, secure, and intuitive at scale.

03

User Research & Data-Informed Design

I leverage qualitative insights and behavioral data to de-risk product decisions. Through continuous iteration and usability testing, I identify friction points in critical journeys.

I also integrate AI tools to accelerate research synthesis and explore design alternatives, allowing for faster, evidence-based decision-making.

04

Design Systems & Scalability

I treat design systems as the backbone of scalable products. By evolving component libraries, I help cross-functional teams maintain consistency and reduce development effort.

This is vital in complex ecosystems where standardizing interactions across physical devices and mobile apps is a competitive advantage.
