ParkLink is a cloud-native, distributed smart parking management platform designed to digitize parking operations and improve the experience of drivers, parking operators, and administrators.

The platform enables users to discover, manage, and reserve parking spaces, while providing operators with tools to manage parking facilities, spaces, vehicles, reservations, payments, notifications, and access control.

ParkLink is built using .NET 10, ASP.NET Core, .NET Aspire, Entity Framework Core, SQL Server, RabbitMQ, MassTransit, Redis, OpenTelemetry, Serilog, Docker, and GitHub Actions. Its architecture follows microservices, event-driven architecture, clean architecture, and production-oriented distributed-system patterns.

Key capabilities

• Identity & Authentication — secure authentication, authorization, OAuth 2.0/OpenID Connect, and identity management.
• User Management — user profiles, lifecycle management, roles, and application-specific user data.
• Vehicle Management — vehicle registration, ownership, classification, and lifecycle management.
• Parking Management — parking facilities, areas, spaces, availability, and parking inventory.
• Reservations — reservation creation, holds, lifecycle management, and availability validation.
• Payments — payment processing, transaction management, status tracking, and payment-provider integration.
• Notifications — event-driven email, SMS, and push notifications.
• Gate & Access Control — parking entry/exit management, reservation validation, RFID, OCR/license-plate recognition, and gate events.
• IoT & Smart Parking — planned integration with sensors and real-time occupancy systems.
