Seren Donu developed foundational backend systems for the SwEng2-2025i/LM18h repository, focusing on scalable architecture and maintainability. Over two months, Seren delivered a multichannel notification API supporting per-user registration and channel preferences, using Python, Flask, and design patterns such as Chain of Responsibility and Factory to ensure robust, configurable message delivery. The codebase was restructured for future extensibility, with modular interfaces and improved testability. Seren also implemented a microservices-based user and task management system with automated end-to-end testing and PDF reporting, leveraging SQLAlchemy and ReportLab. The work established clear service boundaries and enhanced reliability for ongoing development.
