What I'm looking for

I’m looking for a senior role where I can design scalable REST APIs and workflow orchestration services, modernize legacy systems, and deploy/operate on AWS in a remote, agile team—prioritizing reliability, observability, and clean architecture.

I’m a Senior .NET Software Engineer with 8+ years designing, building, and operating production-grade enterprise and SaaS systems using C#, ASP.NET Core, and .NET 6–8. I focus on scalable REST APIs, workflow orchestration, and transaction-heavy backends—while staying hands-on with AWS deployments and day-to-day service operations.

At Upstart, I designed and owned backend services in C# and ASP.NET Core (.NET 6/7) for high-volume workflow execution and long-running jobs. I built and evolved REST APIs using clean architecture and SOLID principles, deployed and operated workloads on AWS (EC2, ECS, S3, RDS, CloudWatch), and integrated AWS-managed services to improve resilience and observability.

I also modernize legacy modules into domain-oriented services, optimize database access patterns, and strengthen background processing to improve throughput and reliability. Previously, I worked on fraud detection and transaction-monitoring (ShieldPay) and source-code analytics (SourceLevel), where I delivered secure APIs, near real-time processing, and data visualizations with React—then continued strengthening performance, monitoring, and CI/CD for frequent releases.
