PROFILE

Seyed Leyla Hosseini

Over a three-month period, contributed to the gocasters/rankr repository by designing and implementing a secure user authentication system with role-based access control. Leveraging Go, PostgreSQL, and JWT, developed RESTful endpoints for login, token issuance, and verification, while integrating configuration management for secrets and token lifecycles. Enhanced the authentication flow to support RFC 6750-compliant Bearer token handling and improved error responses, addressing a critical HTTP status code bug. Established an authentication gateway using Nginx as a reverse proxy, containerized the service with Docker and Docker Compose, and orchestrated infrastructure setup to enable scalable, secure authentication across the platform’s services.

August 2025 Monthly Summary – Rankr (gocasters/rankr) 1) Key features delivered - Implemented a secure User Authentication System enabling login and token-based sessions with role-based access control (RBAC). Technical highlights include JWT generation and verification, config loading for secrets and token duration, HTTP endpoints for issuing and verifying tokens, and a PostgreSQL-backed role repository. 2) Major bugs fixed - No major bugs reported this month. Authentication-related work completed with clean integration into the API, setting a stable baseline for future improvements. 3) Overall impact and accomplishments - Significantly strengthened security posture and client trust by delivering a robust authentication stack with RBAC and token-based access. This enables secure API usage, granular permission control, and scalable user management for Rankr. The work provides a solid foundation for secure onboarding, analytics access, and partner integrations. 4) Technologies/skills demonstrated - JWT-based authentication and token lifecycle management - Role-based access control (RBAC) - HTTP REST endpoints for token issuance/verification - PostgreSQL-backed role repository and secure configuration loading for secrets and token duration - End-to-end security: secure login, token issuance, and verification flows
