I initially contributed to this project by defining the guidelines for developers and documenting the conventions for writing code and creating unit tests. We knew that a lot of the code would be reused in the tvOS application, with this in mind we defined an MVVM architecture that allowed us to reuse the ViewModel classes by both iOS and tvOS, this allowed us to avoid code duplication and accelerate the project.

This project has a special place in my heart, initially there was no Scrum structure, we created the initial working agreements and the process to follow. Over the course of several years, we continuously improved our working method to the point where it became a well-oiled machine that worked very effectively and with little friction, this was one of the project's greatest achievements.

Weight Watchers is one of the most recognized health and wellness brands in the world. I had the opportunity to be part of a complete redesign of their mobile application, modernizing the experience for millions of users across both iOS and Android platforms.

The redesign was a significant undertaking that touched every corner of the app. We adopted SwiftUI on iOS and Jetpack Compose on Android to build a consistent, modern UI layer on both platforms. The result spoke for itself — user retention increased by 6% following the launch of the redesigned experience.

Procore is the world's leading construction management platform, connecting teams across more than 160 countries to manage projects from preconstruction through closeout.

My work focused on a significant architectural improvement: removing a third-party dependency from the chat feature by replacing the chat provider entirely. The migration was executed in three deliberate phases — first replacing the UI layer, then the data sources, and finally the underlying socket connection — ensuring stability at every step. In parallel, we also introduced AI-powered features into the chat experience. The result was a leaner, more maintainable chat system that the team fully owns.

Hot 97 is New York's #1 hip-hop radio station and one of the most iconic brands in music culture. I worked on a major modernization effort across their iOS and Android applications, bringing a legacy codebase up to current standards and expanding what the app could do for its audience.

Beyond the technical refresh, we introduced a new social dimension to the app — users gained the ability to upload and share videos directly within the platform. To support this, we also built a moderation admin website to manage and review user-generated video content. The project culminated in the release of a new version of the app that delivered this richer experience to Hot 97's passionate community of hip-hop fans.

I am not afraid of change, and this was one of those cases where I got to do something different because my experience matched perfectly the job description and I wanted to have a different role than usual.

The goal of the project was to automate the manual regression test suite using XCTest. I was given the task of starting the automation suite from scratch. I faced a few challenges along the way, but I was able to overcome them and successfully automate the test suite. I am proud of the work I did on this project, and I am grateful for the opportunity to have taken on a new challenge.

Greenlight is a company on a mission to help parents raise financially smart kids. They serve more than 6 million parents and kids with a banking app for families.

One of the most impressive aspects of this project was the large number of engineers working on the same application at the same time. Each team was responsible for a specific feature, and my team was responsible for adding credit card features. Thanks to the team's hard work, users can now apply for a credit card from the application and receive it in the comfort of their own homes.

One of the things that I enjoy the most about my work is to create applications that have a direct impact on the lives of others. Davita is a clear example of this. Working on healthcare applications in the United States is always a challenge due to the amount of regulations. In this case, we developed user interface components for an application that was used by nurses to treat patients.

The project was complex, but rewarding. We had to work closely with nurses to understand their needs and ensure that the application was easy to use and safe. We also had to meet a number of regulatory requirements.

In the end, the project was a success. The application was well-received by nurses and helped to improve patient care. I am proud of the work we did and I am glad that we were able to make a difference in the lives of others.

The Sonar Company is a startup founded in Costa Rica in early 2016. The company proposes a data transmission model using sound waves, it was selected to participate in the Comcast NBCUniversal’s SportsTech Accelerator program.

The idea behind the development was to create an application that could detect ultrasonic sounds (inaudible to humans) and transmit data through them. This data could then be converted to different formats, making it potentially useful for television. Users could receive links through the audio emitted by the television, regardless of the content that was being shown.

After experiencing setbacks, I was hired to complete the development of the app because the company hired to develop the app was unable to deliver the desired results. My contribution led to successful tests on television, which resulted in the sale of the company and the transfer of operations to the United States. I was unable to continue with the project, but it was a complex and enriching experience that I am grateful for.
