What I'm looking for

I seek backend or platform roles where I can design scalable, event-driven systems, lead technical execution, and improve reliability and developer productivity.

I am a Senior .NET Software Engineer with 8+ years building and modernizing high-volume backend systems that demand scalability, performance, and reliability across fintech, HR, real-time monitoring, and online sports betting.

I specialize in real-time, event-driven architectures using .NET (C#), microservices, Kafka, RabbitMQ, and containerized deployments; I have led migrations (RabbitMQ→Kafka), monolith decoupling, and built SignalR-based real-time features while publishing reusable open-source libraries on NuGet.

I focus on maintainability, long-term growth, and developer productivity, contributing production-grade solutions, integration testing suites with Docker, and improvements to data models, caching, and authentication flows to unlock new business capabilities.
