Sr. .NET Full Stack Developer @ Citi
About
I am a results-driven Senior .NET Full Stack Developer with 11+ years of experience designing and delivering scalable enterprise applications across Banking, Government, and Healthcare domains. I specialize in building cloud-native systems using .NET Core and ASP.NET Core Web API, developing secure and high-performance REST APIs within Microservices Architecture. My core expertise includes C#, Azure Cloud, Angular, SQL Server, CI/CD pipelines, and event-driven systems using Kafka. I have strong hands-on experience designing modular .NET Core microservices, optimizing SQL Server databases, implementing OAuth2/JWT-based authentication, and deploying scalable solutions on Microsoft Azure using Azure DevOps CI/CD and Docker. Enterprise Experience: • Citi Bank – Built microservices-based AML and compliance platforms using .NET Core, ASP.NET Core Web API, Azure, Kafka, and SQL Server. • State of LA – Modernized legacy WebForms/WCF systems into .NET Core and Angular applications deployed on Azure Cloud. • BCBS – Developed secure healthcare claims systems using REST APIs, SQL Server optimization, and cloud-hosted environments. • IBM – Built enterprise payroll and HR systems using ASP.NET technologies and service-oriented architecture. On the frontend, I develop responsive applications using Angular, React, TypeScript, HTML5, and CSS3, delivering interactive dashboards and workflow-driven enterprise solutions. I enjoy solving complex enterprise challenges by delivering scalable .NET Core enterprise applications that align technology with business goals and cloud modernization initiatives.
