Legacy Stack Migration

Legacy Stack Migration is a Custom Development case study about modernizing an aging application into a maintainable .NET Core and Angular architecture. Many organizations are stuck on older frameworks that slow feature delivery, complicate hiring, and limit cloud deployment options. Migration projects succeed when teams treat them as product modernization — not a weekend rewrite.

According to Wasif Bhatti’s resume project description, this engagement transformed an outdated tech stack by converting the backend to .NET Core and upgrading the frontend with Angular. .NET Core improved performance, scalability, and cross-platform hosting options, while Angular improved interface responsiveness. Web API, Entity Framework, and ADO.NET supported robust data access between the refreshed frontend and backend, with Microsoft Azure used for cloud deployment and resource management.

The practical story is familiar to enterprise clients: critical software still works, but every change is risky and slow. Migration work reduces that risk by establishing a modern API boundary, updating UI delivery to a component-based SPA, and standardizing on Azure for environments and scaling. SQL Server remains the system of record so historical data and reporting continuity survive the transition.

Iwebs Design presents this case with a modern admin-dashboard visual language because that is how stakeholders experience the outcome — a cleaner, more responsive operator interface sitting on contemporary services. We do not invent metrics about “X% faster.” We explain the architectural move and why it matters: better maintainability, clearer frontend/backend separation, and a cloud-ready runtime.

Migration discipline includes incremental delivery, API contracts, and regression-focused testing so business users do not lose capabilities mid-project. The resume stack — .NET Core, Web API, Angular, Entity Framework, ADO.NET, SQL Server, Azure — maps to that discipline. The case study is useful for clients considering whether to rebuild, wrap, or migrate; here the chosen path is a structured modernization onto Microsoft’s current application platform.

For portfolio readers, Legacy Stack Migration signals that Iwebs Design understands enterprise constraints: existing data, existing users, and the need for continuity. It is Custom Development work at the systems level — enabling future features by fixing foundation debt first. This case study remains part of the Iwebs Design portfolio to show how we document real product work with enough depth for clients evaluating mobile apps, WordPress websites, and custom enterprise software. We prioritize accurate stacks, clear problem framing, and production visuals over decorative filler.
