 Introduced necessary technologies and tools for the .NET and Angular – which increased data-fetch speed and end-user-experience in our app-bundles

Reusables created:
 Extended toOdataString implementation (based on Kendo UI) to support extended OData operators
 Created data driven validation library with dynamic error display for angular
 Implemented in-app help (similar to ) for the Angular app-bundle

Technologies used:
 .NET core, Dependency injection, SQL, ORM, Entity Framework, REST API, OData, SignalR

Über mich

15+ yrs of experience - I believe that passion and knowledge us the key to deliver amazing things. Having ex-colleagues (friends) sharing same ideas and mentoring each other helps to keep up with changes within software development. With such experience it’s no wonder that I do provide software development & consultation services (where else could I make more impact)? Wanna hire me?
