Message

At Xyicon, I managed and executed the migration of the core application suite from Windows to Linux, transitioning 20+ microservices. I also upgraded core frameworks from .NET 9 to .NET 10 and refactored the Report Generation Service to use cross-platform libraries.

I designed and maintained cross-platform CI/CD pipelines with Azure DevOps and architected ASP.NET Core services using Entity Framework Core and Azure Blob Storage. Earlier at Hitachi Digital Payment Solutions Ltd., I developed C++ libraries for ATM hardware and built monitoring and PIN PAD key-loading applications.
