Mateusz Krzysztof Gleń

 have extensive experience of working with .NET technology, including ASP.NET, MVC and .NET Core. My favourite frameworks are Sitecore and Kentico. I am also familiar with Umbraco and Optimizely. I can create and utilise elements of CMS, CRM, ERP and online shop platforms. I am also familiar with front-end technologies such as JavaScript, jQuery, Node.js, Gulp, Grunt, Vue.js, Angular and React. I am currently using TypeScript extensively. I develop applications in Sitecore (versions 8.2, 9.3 and 10.3) and Kentico (versions 11, 12 and 13 Experience). I have implemented some Azure applications and services. I can also create pipelines on the Azure Dev Portal. Recently, I upgraded/migrated websites designed using Umbraco, Kentico and Sitecore from older versions to the latest.
