About Me

Passionate about technology and solving complex problems. As a Systems Engineer, my career of over 8 years—6 in the web ecosystem and 2 in mobile development—has allowed me to master the entire software development life cycle.

My journey has taken me from conceptualization and architecture to the deployment and maintenance of high-quality digital products. I specialize in creating dynamic web applications, secure RESTful APIs, and native Android apps with Kotlin and Jetpack Compose.

My focus is on writing clean, scalable, and maintainable code, always applying best practices, design patterns, and modern architectures like Clean Architecture to ensure the success and longevity of each project.
