Our .NET Development Success Stories
Migrating a Legacy Fintech Platform to the Latest .NET Version
Industry: FinTech
Core Technology: .NET, ASP.NET Core 10, C#, Entity Framework Core, Microsoft Azure
A US-based financial services company needed to move a legacy transaction platform built on an older .NET Framework version to a modern architecture. Bacancy migrated the system to ASP.NET Core 10, restructured core modules, and introduced API-based integrations. The result was a faster platform with easier maintenance workflows and the ability to scale with growing transaction volumes.

Integrating AI-Powered Insights into an Enterprise SaaS Platform
Industry: SaaS
Core Technology: .NET, ASP.NET Core, C#, Microsoft Azure, Azure Machine Learning
A UK-based SaaS analytics platform wanted to introduce AI-driven insights into its existing .NET application. Bacancy extended the backend services with AI-enabled data pipelines and integrated predictive models through API services. The platform now delivers automated insights and recommendations driven by AI directly within existing workflows, without requiring the client to rebuild or migrate their core architecture.

Cloud-Native Modernization of a Legacy Manufacturing Platform
Industry: Manufacturing
Core Technology: .NET 8, .NET 10, Docker, Kubernetes, Microsoft Azure
An Asia-Pacific-based manufacturing company relied on a large legacy operations platform built on .NET 8. Bacancy modernized the system by breaking the monolith into microservices, containerizing applications, upgrading the app to .NET 10, and moving workloads to Azure. This helped the client move from a single large deployment to independently deployable services, giving their team more control over releases and system updates.
