I led the project delivering the API for all corporate products and participated in planning the architectural design of certain services used by the corporate application. As a developer, I upgraded the ASP.NET Core framework.

The bank had an Access application which was used by the branch offices as well. As the database became larger, usage became almost impossible.
During the project, all data was moved to a Microsoft SQL Server database. The administrative functions remained in the Access database—which did not contain any data—and a web application was implemented for the branches.
