I implemented advanced functionalities using Java, Spring Boot, Angular 12 and Oracle 11g. Highlights include performance optimization in massive uploads, detailed validation of large data sets from Excel, and the creation of graphs from queries, etc. Generally my contributions focused on improving performance and user experience.

As a freelancer, I have tackled a wide range of projects ranging from the complete redesign of web pages, from the conceptualization and creation of mockups to the final implementation using technologies such as JSF (JavaServer Faces). In addition, I have collaborated in specific cases of backend development to implement missing functionalities in existing projects for various clients. This experience has allowed me to adapt effectively to the specific needs and requirements
