During March 2025, Sergio Luja migrated the logging framework in the BSPQ24-25/BSPQ25-E3 repository from Spring Boot’s default Logback to Log4J2, focusing on enhancing observability and configurability without disrupting existing functionality. He managed dependency updates using Maven, removed the Logback starter, and configured Log4J2 to support finer-grained log levels and structured logging. The migration was delivered with no downtime or functional changes, maintaining compatibility with existing logs and dashboards. Sergio’s work demonstrated a solid grasp of Java, logging frameworks, and configuration management, addressing the need for improved diagnostics and logging performance through careful migration testing and implementation.
