Available to hire
Hi, I’m Dreyfi Ferreira. I’m a Brazilian software engineer based in Adelaide, specializing in mobile development and backend engineering. I’m proficient with Flutter, Dart, and .NET Core, and I’ve built scalable apps and backend systems using Docker, GitLab CI/CD, SQL Server, MySQL, and Firestore. I thrive in collaborative, agile teams and enjoy turning ideas into reliable software solutions.
I work well in Scrum environments and collaborate closely with design teams through Jira and Figma. I’m open to opportunities that leverage Flutter and .NET Core, and I’m eager to explore Node.js and Express.js to deliver impactful, future-proof solutions.
