Minh Le focused on authentication enhancements during March 2025, building hash-based login pathways in the ncc-erp-workflow-w2 repository and integrating Mezon hash authentication in ncc-erp-ams-fe. He developed a new API endpoint in C# for hash-based login, handling DTOs, hash verification, and user management to support alternative authentication. On the frontend, he used React and the Mezon web SDK to implement a custom login hook, streamlining user onboarding and token generation. Minh’s work addressed security and usability by enabling flexible authentication methods, laying a foundation for future identity integrations while demonstrating depth in both backend and frontend development.
