What I'm looking for

I'm seeking opportunities to build backend and frontend solutions, apply clean code and modern architecture practices, keep learning new technologies, and contribute to company growth through strong technical delivery and collaboration.

I'm building software at Mercado Libre using Kotlin, Java, Google BigQuery, Spring Framework, and Go.

Previously, I led full-stack development and support at CBIT, maintaining products, delivering new features, estimating releases, and managing version control with Git and GitLab. I supported continuous deployment on AWS and developed EKS microservices, Lambdas, and REST APIs.

At Sofka Technologies, I delivered and maintained full-stack features, microservices, and REST APIs while supporting customers and end users. My work included Azure deployments, code refactoring, and Java, AngularJS, Spring Boot, Spring Security, Spring Reactor, MongoDB, and Oracle Database development.

I'm a Mechatronics Engineer who applies clean code, SOLID principles, design patterns, TDD, hexagonal architecture, DDD, and reactive development. I also bring experience optimizing PL/SQL stored procedures and migrating data between databases.
