• Built a REST API with a distributed microservice backend — five independent .NET workers (file
processing, avatar processing, notification dispatch, email delivery, scheduled archiving) consuming
domain events via MassTransit over RabbitMQ, keeping the core API decoupled from side effects.
• Integrated JWT authentication and validation to enforce workspace-scoped RBAC (Owner / Admin /
Member) roles.
• Implemented a two-level hybrid cache (in-process MemoryCache L1 + Redis L2).
• Added real-time notifications over SignalR.
• Delivered a React web client for the platform using agentic coding workflows, producing a complete
end-to-end application from API to UI
