Hi, I'm Furkan. A backend developer who builds scalable, testable, and event-driven systems using .NET technologies. I specialize in Clean Architecture, CQRS, RabbitMQ, PostgreSQL, and real-time systems with SignalR/WebSocket. I don't just write working code, I build reliable, scalable systems.

I design backend systems that are:

• ⚙️ Modular and testable with Clean Architecture principles
• 🧩 CQRS + MediatR based command-query separation
• 📤 Message-driven via RabbitMQ (delayed, retry, DLQ)
• 🔒 Secure with JWT authentication & role-based authorization
• 📈 Observability-ready with Serilog, ElasticSearch & centralized exception handling
• 🔁 Real-time capable with SignalR and WebSocket integrations
• 🏢 Multi-tenant aware, supporting both schema-based and row-based separation strategies

Backend:
C#, ASP.NET Core, Web API, CQRS, MediatR, Clean Architecture

Messaging:
RabbitMQ, Event-driven design, Delayed Messaging, Retry, DLQ

Real-time Systems:
