I worked as a Product Designer at Woba alongside product managers, tech leads, and developers to transform the company's B2B experience. My biggest contributions: owning the Design System evolution, readying dashboards to SaaS level, co-founding the Business Platform squad that reshaped the business model, and redesigning internal systems that power operations.

Through my master's and bachelor's research at Universidade de Fortaleza, I investigated voice interaction in digital games and designed frameworks for evaluating gaming experiences. My work resulted in international publications (IEEE SeGAH 2023, Athens) and national recognition (best paper at IHC'19 WiPlay workshop, extended version published in JIS).

I designed a QA system that captures incidents, routes them through review stages, tracks corrective actions, and maintains full audit trail. The challenge: make compliance workflows clear without overwhelming operators.

I designed audit and finance workflows for UNIMED (one of Brazil's largest health cooperatives), giving their operations team clear visibility into exam request patterns and approval bottlenecks.

In partnership with Universidade de Fortaleza and the Public Ministry of Ceará, I led end-to-end design of a portal that automates evidence analysis in criminal investigations.

I designed a 20-month platform that transformed individual blood pressure data into population-level insights for public policy.

I designed an educational app providing medical students with stereoscopic courses on cosmetic procedures viewable through cardboard VR mounts.

In a team of 3 HCI researchers, we investigated how education levels affect voice interaction technology adoption and effectiveness, particularly relevant in Brazil where functional illiteracy is high but voice messaging use is widespread.

I designed a tablet app that transformed the car-buying journey through augmented reality. The Troller Virtual Showroom allowed customers to explore, customize, and visualize vehicles in 3D, then place their configured models in their living rooms using AR.

I helped transform Pathfind's routing planning experience. The existing app handled intensive computational processes but had become unwieldy despite its powerful data processing.

I contributed to the BigData Ceará initiative, a government-driven project focused on improving data transparency and accessibility. My work involved designing dashboards and data visualization frameworks to help decision-makers interpret large-scale public datasets related to health, education, and infrastructure. The challenge was balancing analytical depth with accessibility and usability for diverse stakeholder profiles, from policymakers to technical analysts.
