Designed and developed enterprise-grade applications using C# and ASP.NET Core (.NET 6) in an Agile, regulated financial environment. Built and consumed RESTful APIs supporting financial transactions, data aggregation, and internal reporting, using a layered architecture with dependency injection, SOLID principles, and clean separation across controllers, services, and data layers. Developed secure, responsive front-end applications using Angular 15, TypeScript, HTML5, CSS3, Bootstrap, and JavaScript, including reusable components, reactive forms, validations, and role-based access control. Implemented complex backend business logic with strong focus on data validation, exception handling, and transactional consistency, leveraging Entity Framework Core, LINQ, SQL Server stored procedures, and optimized database schemas and queries for high-volume processing. Ensured application quality through unit testing (xUnit), frontend testing (Karma/Jasmine), and API validation (Swagger/Postman), and deployed applications on Microsoft Azure App Services with environment-specific configurations. Collaborated on secure integrations between Azure-hosted applications and AWS services via REST APIs.

Designed and developed enterprise-grade applications using C# and ASP.NET Core Web API (.NET 6) within an Agile, regulated financial environment. Built and consumed RESTful JSON APIs supporting financial transactions, data aggregation, and internal reporting workflows, using a layered architecture with dependency injection, SOLID principles, and clear separation across controllers, services, and data access layers. Developed secure, responsive front-end applications using Angular 15, TypeScript, HTML5, CSS3, Bootstrap, and JavaScript, creating reusable components, services, and modules with reactive forms, validations, and role-based UI access control. Implemented complex backend business logic ensuring data integrity, exception handling, and transactional consistency, with optimized data access using Entity Framework Core, LINQ, and SQL Server stored procedures. Ensured quality through xUnit, Karma/Jasmine, Swagger, and Postman, deployed applications on Microsoft Azure App Services with environment-specific configurations, and collaborated on secure integrations with AWS-hosted services via REST APIs.

I led the design and development of enterprise applications using C# and ASP.NET Core Web API, supporting state-level regulatory and operational systems. I architected and implemented RESTful services exposing JSON-based APIs to power citizen-facing portals and internal government workflows, while defining and enforcing application architecture standards to ensure a clean separation between presentation, business, and data access layers across multiple projects. On the front end, I developed and maintained responsive and accessible applications using React 17, JavaScript, HTML5, and CSS3, building reusable components, hooks, and service layers to consume ASP.NET Core APIs and improve maintainability. I designed and implemented cloud-native solutions on AWS, deploying backend services on AWS infrastructure and integrating Amazon DynamoDB to support high-availability, low-latency access to transactional and reference data. I implemented secure authentication and authorization mechanisms with role-based access control across APIs and user interfaces. In addition, I led backend development in C#, implementing complex business rules, validations, logging, and exception handling for mission-critical applications. I collaborated closely with database and cloud teams to ensure reliable data integration between relational systems and NoSQL stores, conducted code reviews and technical mentoring, and actively participated in sprint planning, release coordination, and stakeholder discussions, providing technical leadership and delivery oversight throughout the project lifecycle.

I developed enterprise web applications using C# and ASP.NET MVC on .NET Framework 4.7 to support airline operational and internal business systems. I built and consumed RESTful and SOAP-based web services to enable secure data exchange between reservation, scheduling, and operational support platforms. I implemented server-side business logic in C#, handling validations, exception management, and workflow processing to support high-availability airline applications. On the front end, I developed responsive user interfaces using JavaScript, HTML5, CSS3, and Bootstrap, integrating UI components with backend .NET services. I designed and optimized SQL Server database objects, including tables, views, stored procedures, and indexes, to meet transactional and reporting requirements. I performed unit testing using NUnit, along with debugging and performance tuning to improve application stability and response times. I also used TFS for source control and work item tracking, collaborating closely with cross-functional teams in a sprint-based development environment to support production releases.

I developed and maintained enterprise web applications using C# with ASP.NET Web Forms and ASP.NET MVC to support telecom billing and internal operational systems. I implemented server-side business logic in C#, handling data validations and exception management to ensure reliable application behavior. On the front end, I built user interface components using HTML, CSS, JavaScript, and jQuery, ensuring cross-browser compatibility and consistent user experience. I designed and optimized SQL Server database objects, including tables, stored procedures, and views, to support transactional processing and reporting needs. I collaborated closely with business analysts and QA teams on requirement analysis, defect resolution, and sprint-based development activities to ensure timely and high-quality deliveries.
