What I'm looking for

Procuro posições onde eu possa evoluir sistemas legados e web, aplicar boas práticas de engenharia, colaborar em times ágeis e entregar software de alta qualidade.

I have been a software developer since 2011 with a main focus on Delphi (5 to 10.2) and Delphi certification, applying Clean Code, design patterns and unit tests to increase stability and quality of legacy and new systems.

I have experience in evolving and correcting Delphi applications, developing RESTful APIs with Java (Spring Boot, JPA) and dynamic interfaces in React.js, as well as maintaining services in Node.js; I worked with Oracle databases, PostgreSQL and systems integration. Contributed to performance improvements, process automation and integration via APIs, including Java integration to automate time recording.

I am oriented towards agile practices (SCRUM/Kanban), versioning with Git/GitLab and use of tools such as Docker, Jira and Swagger; I look for opportunities that value code quality, system evolution and collaboration in technical teams.
