The existing monolithic .NET Framework 4.8 application struggled to scale under growing user demand (10,000+ daily users), suffered from tightly coupled components that slowed feature delivery, and lacked proper API governance. Issue detection was slow and reactive, leading to extended downtime and poor user experience.

Redesigned the application architecture from monolithic to microservices using Docker and Azure Kubernetes Service (AKS). Migrated legacy .NET Framework 4.8 applications to .NET Core and integrated Java microservices. Implemented Azure API Management for centralized API governance and Azure Monitor with Application Insights for proactive performance monitoring. Built serverless event-driven applications using Azure Functions.

Improved system scalability by 40% and enabled independent service deployments. Boosted application performance by 30% through the .NET Core migration. Reduced issue detection time by 50% and maintained 99.9% application uptime. Reduced infrastructure overhead through serverless architecture. Improved API governance and security across the platform.
