Part-time consultant, carrying out individual and self-managed work on software development and maintenance projects for a music copyright monetary distribution system. Delphi programming language and Monolithic architecture. Oracle database, using PL/SQL, and repositories managed using TFS. In addition, reports were produced with Quick Report and queries and database operations were tuned to optimise performance.

Responsible for managing life insurance and private pension IT systems, leading system development and maintenance projects. Application of good agile development practices with SCRUM and PMBOK, ensuring efficiency and quality at all stages of the project. I worked directly with clients, carrying out detailed analyses of systems and demands, and drawing up proposals for solutions that met their needs and expectations. In addition, I negotiated with suppliers to ensure the delivery of high-quality solutions, trained and led teams, promoting a collaborative and efficient working environment.In a technical leadership role, I defined and implemented software solutions, applying knowledge of architectures such as SOA, Microservices, Monolithic and CQRS. Use of programming languages such as C# and Java, and SOAP and RESTful services to develop robust and scalable systems. Use of Oracle, PL/SQL, SQL Server, T-SQL, DB2 and Elasticsearch databases, and message queues with RabbitMQ. Use of frameworks such as .Net Framework, .Net Core and WCF to ensure adherence to best architectural and development practices. For project management, use of Gantt Charts, Kanban Boards and Eisenhower and UTC matrices, coordinating all project stages efficiently and ensuring customer satisfaction with the results delivered.

Responsible for developing and maintaining systems, covering a variety of responsibilities and technologies. My role included to analyse the system, identify needs and ensure a good relationship with clients. It was necessary to develop and migrate functionalities to a new system, which required in-depth studies of technologies, frameworks, architecture and risk analysis, covering various phases of the SDLC. In addition, I took on the role of Scrum Master, facilitating the adoption of agile methodologies and ensuring the efficiency of development processes. My responsibilities included version control and deploy, as well as refactoring to optimise existing code.During this experience, I worked with various programming languages, including Delphi, C#, WPF and Shell. I used frameworks such as .Net Core, .Net Framework and WCF, and implemented different architectures, such as Microservices, SOA, Monolithic, MVVM, STAR and CQRS. The use of databases involved Oracle, PL/SQL and Elasticsearch, as well as ORMs such as NHibernate. I also configured and used SOAP and Restful services and implemented messaging solutions with RabbitMQ. In report generation, I used Quick Report, DevExpress Report and Kibana.Other relevant activities included tuning database queries to improve performance and applying good practices such as SOLID, SCRUM and PMBOK to ensure development quality and efficiency. Application of TDD techniques for complex and sensitive process evaluations. For effective task and time management, I used prioritisation matrices such as Eisenhower and UTC, as well as visual planning tools such as Gantt Charts and Kanban Boards. This comprehensive experience has given me a deep insight into software development, from conception to delivery, ensuring the implementation of robust and efficient technological solutions.
