What I'm looking for

I’m seeking a senior backend or full-stack role focused on cloud-native .NET development, scalable APIs, mentoring teams, and delivering measurable performance and cost improvements.

I am a Senior .NET developer with over nine years of experience building high-performance enterprise web applications and APIs. I specialize in C#, ASP.NET Core, microservices, and cloud-native architectures, focusing on reliability and scalability.

I've led migrations from legacy .NET Framework to .NET 7, reduced latency and costs through optimized architectures, and implemented containerized deployments with Docker and Kubernetes. I build robust backend systems, design SQL data models, and create CI/CD pipelines with Azure DevOps.

I collaborate closely with frontend teams to integrate Angular UIs and with product owners to translate business requirements into API contracts. I mentor junior developers, conduct code reviews, and champion best practices like SOLID, automated testing, and observability.

My work emphasizes measurable impact: performance improvements, cost reductions, and strong test coverage, while maintaining security standards such as OAuth2/JWT and role-based access control.
