Developed the biggest real estate application in several European countries, known as Imovirtual in Portugal and Otodom in Poland. The app has unique UI flavors that enable users to find their dream property to purchase, rent, or build upon.

Go Live Phone (Elder Monitoring Launcher)

An Android Smart Launcher that was purchased by Vodafone, redesigned for older and disabled people, with tens of integrated apps capable of detecting falls or triggering alerts when outside a specific area.

Malaria Scope

An Android app developed for a redesigned microscope, capable of automating the microscope, moving its stage automatically, and capturing 200 magnified pictures of a blood sample. After capturing each image, it is analyzed using image analysis algorithms, counting the number of white globes and malaria parasites (if found.) The app distinguished different types of malaria parasites, calculated the level of parasitemia, and determined the appropriate medication for a patient.

Analytics App

An analytics wrapper for the Snowplow Analytics analytics tracker.
Snowplow is a complex analytics tool and the client wanted to build a wrapper for Android mobile, tablet, and tv systems to be able to track any of the users' actions.
These cases included articles open, scrolling on pages, and media actions such as play, pause, or close.

Android Engineer at Volvo Cars

Along with 200 other mobile engineers, I worked on the company's mobile app. My team was responsible for the service booking experience in the Volvo Cars app, and we made a number of improvements during my time there: architecture migration, Jetpack migration, modularization, and testing were only some of the big names, but several UI refactors were also included. In the end, it was a new app.
