Over four months, contributed to the woowacourse-teams/2025-ah-madda repository by architecting and delivering a scalable backend for event and organization management. Designed and implemented RESTful APIs for event creation, participation, guest approval, and organization governance, emphasizing robust validation, access control, and auditability. Leveraged Java, Spring Boot, and JPA to establish a production-ready foundation, integrating CI/CD pipelines, Docker-based deployments, and AWS CloudWatch monitoring for reliability and observability. Enhanced group-based communication features, introduced soft delete for safer data handling, and enabled analytics-driven endpoints such as organization activity ranking. Maintained comprehensive API documentation and test coverage to support maintainability and future growth.

Jul 1, 2025July 2025 Monthly Summary — woowacourse-teams/2025-ah-madda Key features delivered: - Backend Foundation: established skeleton with domain entities (Answer, Event, Guest, Member, Organization, OrganizationMember, Question), a BaseEntity for auditing, JPA auditing, and initial validation framework groundwork. - Event Management Core API: implemented core APIs for creating events with validation and scheduling, event participation with guest handling, fetching detailed event information (including questions), and support for event forms and answers; introduced dynamic registration timing and refined access control and error messaging. - CI/CD Automation and Production Deployment: added backend CI script, created CD workflow for development and production, enabling automated builds, tests, containerization, and deployment to Docker Hub and production servers. - Slack Integration Configuration: wired in configuration properties and Slack config file references for future enhancements. - Documentation and quality: Swagger documentation for event and organization domains; added tests to cover previously untested paths. Major bugs fixed and quality improvements: - Added tests for previously untested paths; refined validation, error messages, and access control (e.g., host/guest rules) to reduce edge-case failures. Overall impact and accomplishments: - Built a scalable, production-ready backend foundation that accelerates feature delivery, improves reliability in production, and supports future integrations and governance. Technologies and skills demonstrated: - Java, Spring Boot, JPA/Hibernate, validation frameworks; Swagger; CI/CD, Docker; Slack integration; test-driven improvements.
