Over a three-month period, contributed to the JustJirka/P6PP repository by building a scalable user management and authentication system, establishing a Dockerized ASP.NET Core API foundation with robust JWT-based authentication and role-based access control. Integrated email verification and lifecycle management, connecting with a notification service for secure token delivery and user onboarding. Enhanced data integrity through role seeding, standardized user data responses, and enforced authorization on management endpoints. Introduced CORS policy unification and groundwork for payment integration, ensuring future extensibility. Demonstrated expertise in C#, RESTful API development, and database management, delivering features that improved security, maintainability, and cross-service collaboration.
May 2025 Monthly Summary for JustJirka/P6PP. Key features delivered: - CORS policy configuration and cross-service integration with CorsSettings across AuthService.API and UserService.API; DateOfBirth validation added to the user update flow to improve data integrity and interoperability. - User data standardization and authorization controls: introduced UserResponse for standardized data retrieval and enforced authorization on user management endpoints. - Payment integration groundwork: partial PaymentService implementation with a placeholder for balance creation code to enable future monetization without destabilizing current flows. Impact and value: - Improves cross-team collaboration and reduces integration risk with consistent CORS, standardized responses, and stricter access controls. - Sets the stage for revenue enablement through payments with minimal future integration work, while preserving current stability. Technologies/skills demonstrated: - REST API design, CORS configuration and service integration, data validation, authorization enforcement, and inter-service collaboration. - Incremental delivery and clear commit hygiene evidenced by focused feature work and groundwork for payments.

April 2025 delivered a robust Identity & Access Management framework for JustJirka/P6PP, enabling secure user authentication, email verification, and lifecycle controls (activate/deactivate/delete) with role-based access and data integrity. Integrated with the notification service for verification emails and token-based authentication, and performed interface refactors to support scalable security and frontend integration. Achieved data integrity improvements via role seeding and seeder updates; stabilized CI by temporarily disabling flaky login-related tests to improve test reliability.

March 2025 monthly summary for JustJirka/P6PP. Delivered a foundational user management and authentication backbone that enables a scalable, secure identity layer for downstream services, with Dockerized deployment and cross-service role management. Implemented a complete UserService.API foundation (Users and Roles) with a Get All Users endpoint and a ready-to-extend API surface. Rolled out JWT-based authentication (registration, login via email/username) with improved UX and error handling (401/login fixes). Added Roles Management including creation, retrieval, and assignment of roles, wired through a shared library for consistent authorization across services. Resolved a critical configuration issue to correctly include UserService.API in the ReservationSystem solution, enabling successful builds and CI readiness. These efforts reduce onboarding time, improve security posture, and establish a reusable, service-oriented identity stack for future features.
