What I'm looking for

I seek backend/cloud roles where I can build scalable .NET microservices, lead technical delivery, optimize databases, and contribute to CI/CD and cloud-native architecture in collaborative, growth-focused teams.

I am a Senior Backend Software Engineer with over 10 years of experience designing, developing, and deploying high-performance enterprise systems in finance, manufacturing, and energy sectors.

I specialize in the .NET ecosystem (C#, .NET Core, Entity Framework) and cloud-native architectures on Microsoft Azure, building scalable microservices and secure backend solutions that reduce manual processes and prevent revenue leakage.

My recent work includes leading development of a Gas Station Sales Management System, real-time data synchronization with SignalR, processing 100,000+ daily sales records, and deploying services with 99.9% uptime on Azure.

I am results-driven, focused on system efficiency and business impact, with hands-on experience in containerization (Docker, Kubernetes), CI/CD, database optimization, and prototyping analytics/AI modules to inform product and operational decisions.
