I am old certificated .NET/C# programmer working with .NET 20 years. Last 7 years I was working on support of large responsive, multilingual hybrid applications (ASP.NET MVC + Angular) and front-end programming is not a problem for me. I am working and feel free with C#, GO, JavaScript (ES5, ES6), jQuery, Bootstrap, Material, TypeScript, RxJS, NgRx, CSS3, HTML5, AngularJS, Angular 8+, Blazor.
Knowing well HTML5, CSS3 and JavaScript I shall build your pages. Only HTML5 tools (DOM API, WEB Components, Fetch API) will be used.
