My responsibilities at Upax include writing, reviewing, maintaining and upgrading high performance, reusable and reliable code working on a 100,000 users application on a squad of 12 developers on an agile environment.

With my experience at Upax, and the one I obtained over the years, I have gained a strong foundation on iOS native development using Swift. I have developed a deep understanding of the iOS platform and have experience with various tools and technologies used for iOS development, including the iOS SDK and Apple's design principles, as well as different frameworks and design patterns.

Working on an application consisting of 35 different modules and serving over 100,000 active users was a unique and challenging opportunity that allowed me to make a significant impact on many people's daily work. 

One of the biggest challenges I faced was maintaining the application's performance and reliability, given the high volume of users and the wide range of functionality it provided. I was proud to be a part of the team that was able to deliver a high-quality application that met the needs of its users and the company expectations.

In my daily work I was part of a dynamic and fast-paced agile environment, where I had the opportunity to participate in all aspects of the SCRUM process from a remote environment.
