New York, NY

As a Senior Full Stack .NET Developer, I contribute to Citi’s global payments platform by developing and enhancing scalable microservices using .NET 8, C# 12, and ASP.NET Core Web APIs, Angular 16(Typescript, RxJS) and Blazor to support high-volume financial transaction processing. My work focuses on strengthening system performance and reliability across distributed services through SQL Server optimization, efficient API design, and event-driven integrations using Kafka. I collaborate with cross-functional engineering and DevOps teams to deploy containerized applications on Azure and AKS using Docker and CI/CD pipelines, ensuring stable releases and faster delivery cycles. I also support secure enterprise integrations by implementing OAuth2, JWT authentication, and Azure AD-based authorization, while building operational dashboards that provide real-time transaction visibility and compliance monitoring.
