About

Professional summary

I am a Web & Mobile Developer based in Montevideo, Uruguay, with hands-on experience building native Android, cross-platform mobile, and web applications.

I specialize in Kotlin, Flutter, React, and modern Android development. My work includes Jetpack Compose, Kotlin Multiplatform, Compose Multiplatform, and native Android UI development with XML.

I am experienced in implementing clean and scalable application architectures, including MVVM, MVP, and MVI. I also work with dependency injection, RESTful API integration, asynchronous programming with Coroutines and Flows, and local persistence using Room and SQLite.

In cross-platform development, I have delivered responsive and high-performance interfaces with Flutter and validated APIs and endpoints using Postman. I also have backend and web development knowledge with Node.js, Express, MongoDB, JavaScript, and SQL.

I bring analytical experience from sports data collection and predictive-model analysis, which has strengthened my problem-solving and data-driven thinking.

I am looking to continue growing in a collaborative and challenging environment where I can contribute my technical expertise, adaptability, and passion for building impactful digital products.
