Professional summary

I am a software engineer with experience designing enterprise applications, cloud orchestration services, and automation platforms. I specialize in building reliable, scalable software for complex business workflows.

I develop C# and .NET microservices, REST API integrations, and React-based applications. My backend experience includes .NET Core, ASP.NET, dependency injection, Polly, Node.js, and Express.js.

I have hands-on experience with Azure, Azure DevOps, Jenkins, CI/CD pipelines, and multi-cloud infrastructure automation. I have used Azure CLI, AWS SDK, VMware APIs, and IIS to support provisioning, orchestration, and operational management services.

I modernize legacy RPA workflows into maintainable C# automation services and implement unit and integration testing strategies to improve software reliability. I have also worked with Selenium, WinAppDriver, Azure Functions, and Azure Logic Apps.

My background includes tax technology, accounting workflow platforms, and cloud infrastructure management. I collaborate with cross-functional teams to gather requirements and deliver scalable automation and enterprise integration solutions.
