Karo

Karo is an original browser-based multiplayer strategy game played on a shared 19-region hex board. Three or four players collect Supplies, build Trails, Camps, and Strongholds, trade through banks, harbors, or direct offers, use Development Cards, move the Warden, and compete for Victory Points. ASP.NET Core services validate actions and synchronize viewer-specific match state through SignalR.

  • Backend-validated SignalR actions and viewer-specific state.
  • Deterministic board topology for construction, harbors, production, and scoring.
  • Complete base rules plus optional scenarios, Tactics, and Public Ambitions.

PawConnect

PawConnect connects public dog discovery and adopter workflows with the operational work performed by shelters. Its React and TypeScript portal handles discovery, profiles, favorites, saved searches, adoption applications, notifications, and Adoption Copilot, while the established Blazor application supports Shelter, Volunteer, and Admin operations. Both clients reuse the same ASP.NET Core services, Identity security, Entity Framework Core persistence, and SQL Server data.

  • Multi-client adoption and shelter workflows over one shared backend.
  • React adopter portal with generated API contracts and secure cookie authentication.
