At Opensoft, I develop and maintain a large-scale Portuguese government web platform used by more than 10 million registered users. I work across Java and Spring backend features and React components.
I also develop reusable software libraries shared across applications, implement REST endpoints, and optimize Oracle SQL queries and data-access logic to reduce execution time.
I write automated tests with JUnit and troubleshoot production issues. I work with an Agile Scrum team, taking part in sprint planning, daily meetings, and retrospectives.
