Diabetes Logs

This Swift-based app is intended to help diabetes patients log their blood sugar values and medication.

I developed the iOS and Android client apps from scratch. The iOS app also has a Watch Companion app, and its user interface (UI) is adapted for iPad screens. I used Firebase for the back end.

It grew from a side project into something people use every day, and it helps them keep their diabetes in check.

Burger King App

A food delivery and ordering app for the Burger King franchise in Spain and Portugal. I worked as part of an iOS team that redesigned and maintained the app.

I was involved in almost all aspects of the app from inception. Some of the decisions I helped make during the development process have shaped the apps into what they are today.

I also helped the team streamline the process of developing and distributing the apps.

Popeyes App

An app for food delivery and food ordering for the Popeyes franchise in Spain.

I worked on the iOS team that built the app from scratch and maintained it. I was involved in all aspects of the app, from code structuring and architecture to CI/CD flows.

An Objective-C-based app for the listeners of Radio Classique in France.

I was involved with re-designing the UI of the app based on provided mockups as well as adding features to the app, such as an alarm mode and radio stream switching.

Wistrip App

A Swift-based app for people that go on train trips in France.

I was part of the iOS team that launched the app in the first stage. I was involved with changing different functionalities of the app before launch as per the client's request. These included changing the business logic of the app and modifying its UI.
