I actively contributed to cloud deployment and DevOps processes using Azure App Services and Azure DevOps YAML pipelines. I supported production systems through monitoring and troubleshooting using Application Insights and Log Analytics, participated in Agile Scrum ceremonies, collaborated with cross-functional teams, and handled end-to-end delivery from requirements to production support.

Worked as a .NET Full Stack Developer at Citibank, Chicago, Illinois, from January 2019 to November 2020, contributing to a Digital Banking Microservices Platform. The application supported customer profile management, preferences, and alert-related functionalities for digital banking users, along with internal banking operations teams. The focus was on security, performance, scalability, and compliance.

From the backend side, I designed and developed RESTful APIs using C#, ASP.NET, ASP.NET Core, and MVC architecture. I worked on modular components following clean coding practices and service-oriented design. Business logic was implemented with proper validation, exception handling, and audit-friendly logging, ensuring reliable and compliant banking workflows.

On the data layer, I worked extensively with SQL Server using Entity Framework and EF Core for transactional operations, along with Dapper and ADO.NET for performance-critical queries. I also supported integration with legacy Oracle systems to synchronize customer data across modern and existing banking platforms, maintaining consistency and data accuracy.Embedded Crystal Reports within ASPX-based financial portals for audit and reconciliation reporting.

Optimized SQL Server stored procedures to support high-volume financial reporting workflows.

From the frontend side, I developed responsive user interfaces using Angular, TypeScript, RxJS, Angular Material, HTML, CSS, JavaScript, Bootstrap, and Ajax. These interfaces enabled secure and user-friendly screens for managing customer profile information and preferences, with smooth API integration and client-side validations.

I actively worked in an Agile Scrum environment, collaborating with business analysts, QA teams, and product owners. I also contributed to unit testing, API testing, CI/CD activities, version control, and production support, ensuring stable releases and continuous improvements across the application lifecycle.

I worked as a .NET Full Stack Developer on a Policy Administration Modernization project focused on improving how insurance policies were serviced for agents and internal users. The goal of the project was to modernize legacy systems and enable faster policy lookup, endorsements, renewals, and document generation, while maintaining accuracy, compliance, and system stability.

I was involved in the full SDLC and followed Agile Scrum methodology, participating in sprint planning, daily stand-ups, and sprint reviews. I designed and developed applications using ASP.NET MVC on .NET Framework, and worked on backend components that supported policy servicing workflows and transaction processing.

As part of system integration, I worked with SOAP-based web services and XML to communicate with legacy policy and claims systems. I collaborated closely with business analysts to understand insurance rules and implemented validation logic to ensure policy eligibility, coverage accuracy, and regulatory compliance during policy updates.

On the frontend, I developed interactive and user-friendly screens using HTML, CSS, JavaScript, jQuery, and Ajax. These screens allowed agents to search policies, submit endorsements, and view updates in real time, improving usability and reducing manual effort.

I also worked with SQL Server using ADO.NET for data access and performance tuning. I implemented logging and exception handling using Log4Net, wrote unit tests using xUnit, managed source code with SVN, tracked work in JIRA, and supported production deployments and post-release application support using Visual Studio.

I started my career as a .NET Developer at TCS, working on enterprise web applications developed for internal business users. The primary business objective was to replace manual and Excel-based processes with a centralized web application to improve data accuracy, reduce manual effort, and support day-to-day business operations.

From a technical perspective, I worked on full-stack development using ASP.NET WebForms and .NET Framework. I was responsible for developing backend logic using C# and ASP.NET, implementing validations, handling data processing, and ensuring smooth interaction between application layers.
