Worked on SwaplyAr-Backend-02, delivering a modular bootstrap setup and standardizing path aliases to enhance maintainability and scalability of the backend. Applied NestJS and TypeScript to decouple bootstrap logic, simplify imports, and refactor code structure for improved readability. Expanded test coverage for seeders and assets, increasing reliability and supporting future development. Addressed legacy issues by fixing the nodemailer mock setup and centralizing admin seed identity, which stabilized the test suite. Adopted enum-based path aliases and standardized JSONB defaults, laying a robust foundation for scalable feature growth while ensuring the codebase remains testable and easier to extend over time.
