In this app, you can save, manage, and share information about your own health with your doctor or practitioner. Patients can always have their health data to hand on a smartphone: for a lifetime, free of charge, and certified to be secure. I was part of the iOS team in charge of building robust and secure features released in a fast-paced environment for the health industry. I worked on the development of the app and ensured a clean architecture in order to end up with a product easily scalable and adaptable for any market. I created many reusable custom UI components separated into CocoaPod repos. I also made use of Unit Testing, UI Tests, and continuous integration tools to ensure a high-quality product released in a fast development context.
This is a custom-designed mobile application to fit into anesthetists' daily workflow. It is part of CGM MEDISTAR 4A, an overall solution for anesthetists, their practice administrators, and billing clerks. It makes provision for all anesthetist workflow scenarios: individual anesthetists, group practices, and associations as well as bureaus. I took the existing source code and brought it to the stage where it could be released with success as a product serving in the health industry. My role was to build features that make use of sensitive data in an offline and thread-safe manner and to keep the offline storage in sync with the main server using complex asynchronous concepts. Functional reactive programming and native async operations were used for the sync process and Realm SDK was used for offline capabilities. I was also in charge at first with researching and then implementing iOS-specific features like notifications, calendar events, location-based alarms, and watchOS integration.
Rubberduck is an app that gets users their own mechanic in pocket format. It assists with the maintenance of your car, and now provides the following services: mobile tire change, service inspection, tire sales. Acted as Sole Developer for the project, taking a simple idea and bringing it to life in a short period of time as a clean and nice interface that surprises with some cool animations done using the Core Animation framework. The complexity was given by the integration of push notifications, Google Maps SDK, payment solutions like Stripe, and chat solutions like SendBird and Firebase.
