Betterfly is the leading digital benefits platform in Latin America (Chilean insurtech unicorn), combining physical, mental, and financial wellness with insurance protection and social impact. It rewards healthy habits with charitable donations and automatically growing insurance coverage, empowering companies and employees across multiple LatAm countries. As a Senior Software Engineer specialized in Flutter, I contribute to the development and optimization of the cross-platform mobile application, applying Clean Architecture and state management with GetX to ensure scalable, maintainable code aligned with business goals.

Key responsibilities and contributions:

• Implemented critical features for gamification, corporate benefits, and personalized experiences, integrating multiple high-concurrency REST APIs.
• Defined and drove the testing strategy (unit and widget tests), achieving >85% code coverage and reducing production errors.
• Optimized the development process using GitHub Copilot, accelerating deliveries while reinforcing best practices.
• Ensured code quality through code reviews and strict internal Flutter standards.
• Collaborated with Product Managers, stakeholders, and design teams on Scrum roadmaps, prioritizing UX and high-value deliveries.

This experience strengthened my expertise in high-impact mobile development in fintech/insurtech environments, focused on scalability, security, and end-user experience.
