Created secure and scalable RESTful APIs in C# and optimized database performance through stored procedures and ORM-based query tuning. Migrated applications to Microsoft Azure, enabling cloud deployment, monitoring, and production readiness. Implemented dynamic query frameworks using Expression Trees to generate runtime filters, sorting, and projections, and resolved EF Core query translation issues by restructuring LINQ into SQL-compatible patterns. Applied runtime type generation and dynamic projection models to support evolving data requirements while controlling memory usage through caching strategies. Developed responsive dashboards using React, Material UI, and Tailwind CSS, integrated telemetry via Azure Application Insights, monitored using KQL, and improved code quality using SonarQube, unit testing, and CI/CD automation.

Developed and maintained enterprise web applications using ASP.NET MVC5, Web API, and Entity Framework, delivering secure and scalable solutions across the full SDLC. Built responsive front-end screens and Single Page Applications using Angular 5 (CLI, Material, routing, directives, reactive forms) and enhanced UI workflows with validations, caching, and reusable user controls. Designed and implemented RESTful services supporting GET/POST/PUT/DELETE operations, integrated backend data using SQL Server stored procedures, and improved performance through optimized database design and fine-tuned objects. Implemented authentication and authorization using JWT, OAuth, role-based security, session/cookie management, and developed WCF services for entity search and integration. Leveraged NodeJS for build automation and server-side enhancements using tools like Grunt, Gulp, Webpack, and created CI/CD build and release pipelines in Azure DevOps. Supported cloud integrations using Azure Functions, performed unit and integration testing with a TDD approach, created test plans, resolved production bugs, and generated reports using SSRS for business insights.

Developed and maintained healthcare web applications using VB.NET and ASP.NET Web Forms, improving key workflows such as patient data management, appointment scheduling, and medical record retrieval. Collaborated with stakeholders to gather requirements, perform detailed analysis, and translate business needs into new application features. Built user-friendly interfaces and implemented both front-end and back-end functionality to support seamless user interaction and data processing. Designed and developed modules using C# (.NET 4.5.1), ensuring reusable components and clean architecture aligned with technical specifications. Developed and optimized SQL Server backend logic including stored procedures, cursors, triggers, and functions to enable real-time data integration. Implemented page-level error handling using custom error pages, logging, and activity tracking to improve system reliability. Created summary and survey reports using RDLC reporting, supporting business insights and operational needs. Managed source control using Git, handling merges, branching, and version tracking. Supported deployments by hosting applications on Windows servers and improving UI responsiveness with AJAX-based ASP.NET controls.

Designed and developed web applications using ASP.NET MVC and ASP.NET Web Forms, creating consistent site-wide layouts with Master Pages and content pages. Built responsive and visually appealing interfaces using CSS and XHTML, ensuring a clean and user-friendly experience. Implemented robust data access and reporting features using ADO.NET, including extensive use of DataSets, DataTables, DataAdapters, and GridView controls to display backend data efficiently. Developed ASP.NET modules (ASPX) and reusable user controls, leveraging server controls, validation controls, and state management techniques to support secure and optimized application behavior. Worked with Web Services, caching mechanisms, and IIS-based deployments to enhance performance and reliability. Enhanced user interaction through jQuery AJAX calls using GET/POST, parsing XML/JSON responses for dynamic UI updates. Implemented login security features using AJAX Password Strength controls and created custom AJAX components such as a Phone Validator for input validation. Also gained exposure to WPF development and maintained code using TFS for version control and team collaboration.

Worked as a .NET Developer developing and maintaining healthcare web applications using C#, ASP.NET Web Forms, and .NET Framework. Designed layered architecture components and built WCF and SOAP-based services to enable secure communication between healthcare systems. Developed and optimized SQL Server stored procedures, triggers, and queries for performance and data integrity. Implemented role-based authentication and authorization to protect sensitive healthcare information. Contributed to requirements analysis, technical design, development, testing, and production support. Collaborated with cross-functional teams to deliver scalable, secure, and maintainable applications aligned with healthcare compliance standards.
