Worked on the Immpression-Dev-Team/backend repository to enhance authentication security and streamline backend code. Focused on unifying password hashing for both user and admin authentication by standardizing bcrypt usage, replacing previous implementations with consistent logic across models and routes. Addressed a security regression caused by the removal of Argon2, identifying the introduction of plain-text password storage and planning remediation to restore proper hashing. Improved code maintainability by consolidating imports and refactoring password verification processes. Removed sensitive information from logs to prevent exposure of hashed passwords. Utilized JavaScript, Node.js, and Express.js to deliver a more secure and maintainable authentication system.
March 2025 (Immpression-Dev-Team/backend): Strengthened authentication security and code hygiene by standardizing password handling with bcrypt across User and Admin flows, while consolidating imports and hashing/verification logic for easier audits and maintenance. Delivered a security-focused refactor that reduces fragmentation in credential handling and sets a trustworthy foundation for future hardening.
