Sandra Sillanpää
Contributed to the Slowers-App repository over four months, delivering thirteen features and addressing key reliability and security needs. Developed backend persistence using MongoDB and PostgreSQL, integrated Cloudinary for image handling, and enhanced user authentication and onboarding flows. Applied Go, JavaScript, and TypeScript to implement API endpoints, asynchronous workflows, and robust error handling. Improved CI/CD pipelines with Docker and GitHub Actions, strengthened security by mitigating vulnerabilities, and expanded test coverage using Jest and Vitest. Refactored legacy code, streamlined database management, and introduced internationalization and UI/UX improvements, resulting in a more maintainable, scalable, and user-friendly full stack application.
