What I'm looking for

I seek senior backend or cloud roles where I can design secure, scalable systems, lead best practices, and work in distributed Agile teams with opportunities for mentorship and impact.

I am a Senior Backend Engineer with 12+ years designing and delivering scalable, secure backend systems across healthcare, finance, and enterprise domains. I specialize in .NET, C#, ASP.NET Core, RESTful APIs, distributed systems, and cloud-native architectures, with a strong focus on performance, reliability and security.

I have led backend architecture and delivery, built CI/CD pipelines, and integrated complex external systems using OpenID Connect and other interoperability standards. My recent work includes designing national health portal services, real-time data exchange, and enterprise-grade authentication and authorization.

I mentor engineers, establish backend best practices, and collaborate in Agile cross-functional teams to improve code quality and system reliability. I am comfortable with Azure, SQL Server, Cosmos DB, messaging systems like RabbitMQ/Kafka, and testing frameworks such as xUnit and NUnit.
