Project history
Worked on multiple Angular + C# .NET / EF Core applications and legacy ASP.NET applications, remote.
Worked on the upgrade of an AngularJS + Ruby on Rails application. Converted the application from Coffeescript to TypeScript, Slim to HTML, Rails to API-only mode, and AngularJS to hybrid AngularJS + Angular. Remote.
Worked on a public-facing web application (Angular, ASP.NET Core, EF Core, PostgreSQL). Developed reusable components using PrimeNG. Some exposure to Kubernetes (Helm Charts) and Azure DevOps environment. Remote.
