Full Stack .NET Developer building secure enterprise web apps with C#, ASP.NET, Angular, and SQL Server.
United StatesWhat I'm looking for
I’m a Full Stack .NET Developer with 4+ years of hands-on experience designing, developing, enhancing, and supporting enterprise web and client-server applications in production. I focus on backend services and reliable API-driven communication, grounded in Object-Oriented Programming and layered architecture principles.
In my recent role, I design and enhance enterprise web applications using C#, .NET Core, ASP.NET MVC, and ASP.NET Web API. I build responsive Angular frontends with HTML5, CSS3, JavaScript, jQuery, AJAX, and Bootstrap, and I implement authentication/authorization with JWT-based security to protect APIs and application features.
I bring strong data and integration experience through Microsoft SQL Server—writing and optimizing queries, stored procedures, functions, triggers, and views—plus RESTful API development for secure, consistent, and efficient frontend-to-backend communication.
I’ve also worked with Microsoft Azure for deployment, configuration, monitoring, and CI/CD using Azure DevOps and Git, within Agile/Scrum teams across the full SDLC. I’m energized by cross-functional collaboration with business, QA, and developers—from requirements through production support—and by delivering improvements through refactoring, modernization, and defect resolution.
