Over a two-month period, contributed to the Madrid-Team/PlanMate repository by building a secure user authentication and login system, followed by a comprehensive user creation flow spanning data source, repository, and use case layers. Applied Kotlin, Java, and MongoDB to implement password hashing, input validation, and robust test coverage using TDD principles. Refactored project architecture for maintainability, improved test infrastructure, and expanded coverage to include admin tooling and data management scenarios. Addressed regressions with targeted fixes and enhanced code hygiene through cleanup and dependency updates. The work established a reliable authentication foundation and streamlined backend processes for future extensibility.
May 2025 (Madrid-Team/PlanMate): Delivered a cohesive user creation flow across DataSource, Repository, and UseCase, reworked project architecture for cleaner maintenance, and expanded the test suite to improve reliability across authentication, admin tooling, data sources, and domain use cases. Addressed regressions with targeted fixes and enhanced test infrastructure with modern tooling and better packaging to reduce risk in release cycles.

April 2025: Delivered a complete User Authentication and Login System for Madrid-Team/PlanMate, consolidating all login-related changes into a single user-facing feature. Implemented the domain use case, repository integration, and password hashing with input validation; added tests to validate login flows; refined the use case logic to improve reliability and security. This work establishes a secure authentication foundation and prepares the ground for future session management and authorization features.
