Android developer passionate about creating high-quality mobile applications.

What I'm looking for

I seek opportunities that foster professional growth and allow me to work on innovative mobile applications.

I am a committed Android developer with a robust foundation in Kotlin and a strong passion for mobile application development. My expertise extends to Dart and Flutter, enabling me to deliver efficient cross-platform solutions. Although I specialise in native Android development, I continuously pursue growth in modern technologies such as Jetpack Compose and Kotlin Coroutines.

I am currently employed as an Android Developer at Banco Hipotecario, where I contribute to the design and implementation of secure, high-quality features for the bank’s mobile applications. My responsibilities include integrating critical services, ensuring performance optimisation, and collaborating with cross-functional teams to maintain a seamless user experience within a regulated financial environment.

Previously, I served as a Junior Android Developer at FlexTech, where I was instrumental in developing new functionalities for a task management application. In this capacity, I integrated Firebase for authentication and real-time data storage, adopted the MVVM architecture to enhance code organisation, and worked closely with design teams to guarantee an intuitive user interface. I take pride in my capacity to address complex challenges and deliver solutions that elevate user satisfaction.

Prior to that, I worked at AppDev Lab, contributing to the development and upkeep of a personal finance application. My focus there centred on maintenance tasks and performance optimisations, which collectively resulted in a markedly improved user experience. Highly motivated to advance professionally, I consistently seek opportunities to add value to every project in which I am involved.
