DroneLog

DroneLog is an EASA-compliant flight-logbook platform for drone operators, built as a technical showcase of clean architecture on .NET 8.

Architecture#

• Multi-tenancy enforced at the data layer: row-level isolation through EF Core global query filters resolved from JWT claims, so a tenant can never read another's rows even if a query forgets to scope itself.
• Policy-based RBAC across three roles — Admin, Instructor and Pilot.
• An EASA compliance engine using a Result<T> pattern to make rule violations explicit rather than exceptional.
• Real-time notifications over SignalR, and licence-expiry warnings scheduled with Hangfire.
• PDF export via QuestPDF; file storage on Azure Blob Storage.

Testing and delivery#

69 tests: unit tests with xUnit, FluentAssertions and NSubstitute, plus integration tests against a real SQL Server via Testcontainers. CI/CD runs on GitHub Actions with Docker Compose.
