What I'm looking for

I’m looking for a senior full-stack .NET role where I can modernize legacy systems, design secure REST APIs, and build event-driven, cloud-deployed platforms with strong CI/CD and reliability.

I’m a Senior Full Stack .NET Engineer with 8+ years building high-performance, scalable enterprise systems for platforms serving 500+ clients. I specialize in REST API design, modernization of legacy .NET systems, and delivering full-stack features—from database to UI—using .NET Core/.NET 6+/.NET 8 and ASP.NET Core Web API.

In my roles, I’ve shipped 20+ scalable REST APIs, reduced query execution time by 45% through SQL Server tuning, and refactored 8+ legacy .NET modules into modern services. I build secure, event-driven architectures with Kafka and Elasticsearch, implement JWT-based authentication and role-based access patterns, and run high-availability deployments with Azure/AWS, Docker/Kubernetes, and Azure DevOps CI/CD—supporting 30+ production releases with zero critical downtime.
