United StatesWhat I'm looking for
I’m a Senior .NET Engineer with 12+ years of experience designing, building, and maintaining enterprise-grade .NET applications in high-availability, mission-critical environments. I’m deeply focused on backend systems, API development, authentication/authorization, and production reliability—using structured root cause analysis and system-level debugging to diagnose and resolve incidents quickly.
In my recent role, I led the design of microservices-based architectures and built cloud-native services with ASP.NET Core Web API, C#, and .NET 8 to support high-volume financial transaction processing. I’ve delivered secure identity and access management using OAuth2, JWT, and Azure Active Directory, improved observability with Application Insights, Azure Monitor, Serilog, Kibana, and Grafana, and supported scalable deployments across Azure Kubernetes Service (AKS) and AWS EKS using Docker and Terraform. I also mentor engineers, lead technical discussions, and strengthen engineering standards across Agile teams.
