Junior backend software developer focused on Java, C#, and SQL Server, optimizing databases and building scalable services.

What I'm looking for

I’m looking for a backend role where I can refactor legacy systems, optimize high-scale databases, and build Spring Boot microservices with hexagonal architecture in an Agile (Scrum/Kanban) team.

I’m a Junior Software Developer with a strong backend foundation in Java, C#, and SQL Server. I’m currently refactoring complex systems and optimizing massive databases in high-availability environments, with a clear focus on scalable, robust solutions.

I work with architecture and quality principles, digging into Spring Boot, arquitectura hexagonal, and microservicios to build maintainable systems. My approach is strongly oriented toward clean, structured software and continuous improvement.

In my Junior Software Developer (Internship) role with ICP (Feb 2026–Actualidad), I optimize business logic in critical logistics systems to improve scalability and maintain legacy code. I also refactor Stored Procedures (T-SQL) across many servers, ensuring data integrity and system performance, and I handle debugging and functional testing for production-impacting changes.

I’m an autodidact and proactive engineer in training (Estudiante de Ingeniería Informática, próximo inicio/matriculado Octubre 2026). I’m eager to keep learning while delivering dependable backend solutions in Agile teams using Scrum/Kanban.
